I have my own site at www.bayes.co.uk and my XML/XSL Portal where I demo my
skills and new technologies although I don't always have time to keep them bang
up to date. This has been invaluable as most websites I have developed have
been intranets and not visible to the public.
I have in depth knowledge of most W3C/browser
technologies and have tried to address compatibility issues in my own site
which should be viewable by both Netscape/Firefox and IE3/4/5/6. I have an
understanding of WAI and have done some work with the R.N.I.B.
I have in depth knowledge of most server
technologies from web servers to databases and have developed in VB,
JavaScript, ASP, c# and Perl.
I am also very active in various mailing
lists to do with XML/XSLT/SVG and am one of the top contributors to the XSL-List
although I haven't recently.
For the last year or so I have been doing
many small consultancy jobs rather than a solid contract. These have covered
WEBDAV, SOAP web services, Digital Dashboard, training and book reviewing. I
have done consultancy work analysing appropriate technologies to provide
solutions in WEBDAV related areas. I have worked on Digital Dashboards as part
of DDRK 3 as well as Sharepoint Portal Server and more recently WSS.
I am mainly interested in jobs that allow me
to use my XML/XSLT skills to the full.
This assignment was to develop a ticketing
portal for SE trains and NBTS corporate customers.
The system consists of two ASP.NET front ends
and a Web Services/SQL Server ticketing queue backend.
The first configurable and rebadgeable front
end allows corporate customers to order season, multiple rail journey and tube
tickets within the South East region and Europe. It allows for various
addressing schemes and cost centre handling. Ticket requests can be sent
directly to NBTS or sent to a supervisor for authorisation by email or using
the web based front end. It also contains various administration modules to
allow company administrators to add users, modify company specific roles and
configure, modify and bulk upload company data.
The second front end allows NBTS to action
queued tickets. Queued tickets can be sorted by various criteria such as company,
ticket type and urgency. Once complete the physical ticket is printed and
mailed to the customer. It provides a simple interface to add new corporate
customers and configure various features of the customer's website, manage
customer permissions and roles, bulk upload company data and manage queued
tickets.
The backend consists of several Web Services
for inserting ticket requests into the queue and querying submitted ticket
requests. Once the ticket request has been submitted to the queuing subsystem
all interaction with the ticket request is handled via web services. Although
the Web Services are currently only used by the NBTS corporate portal and
SETrains internet ticketing portal the plan for the future is to allow
competent authorised corporate customers to interact with them directly.
Technologies Used: XML/XSLT, Web Services,
SQL Server, C#.NET, ASP.NET, HTML, CSS, JavaScript
This assignment was to develop 'GDS'
component and web services link to Global Distribution Systems (specifically
Galileo) for Anteeo Solutions' product TMS. TMS needed Web services Galileo
(and Amadeus).
The assignment involved the design and
development of a COM component and Web Services environment for TMS (VB6) to
communicate with airline GDS and other systems using XML for the purpose of
obtaining availability and making bookings within the third party systems. The
assignment included the establishment of specific dialogue with the 'Galileo'
system.
As well as the basic COM component I
developed various testing, support, SQL Server stressing and maintenance
applications.
In the last month of the contract I created
the new
website using ASP.NET.
Technologies Used: XML/XSLT, XML Schemas, Web
Services, VB.NET, C#.NET, ASP.NET, HTML, CSS, JavaScript
For the last year or so I have been doing
many small consultancy jobs rather than one solid contract. These have covered
WEBDAV, SOAP/Web Services, Digital Dashboard/SharePoint Portal server Web
Parts, Training and book authoring/reviewing. Programming mainly in c#.NET but
also VB.NET I have worked on many ASP.NET websites some of them based on the
IBuySpy Portal, and various bespoke content/document/information management and
data aggregation/integration systems. Much of the work has involved building
discreet custom components for ASP.NET or SharePoint Portal server on the
client side and data feed transformations on the server side.
Companies I have worked for include On-Idle,
IBS, Ikhaya and Wrox.
As well as working for various clients I have
been working on 2 or 3 large projects in the content management field. Although
it is difficult to go into details these run along similar data
acquisition/transformation/client presentation lines as I have done for
clients.
Technologies Used: XML/XSLT, XML Schemas,
SOAP, Web Services, WEBDAV, Web Parts, VB.NET, C#.NET, ASP.NET, JavaScript,
HTC, Behaviours, VSS, RSS
Vizzavi Limited is a joint venture between
the Vivendi Universal and Vodafone groups of companies to build a new
multi-access (Internet services, mobile data and interactive television)
European portal.
Initially employed as an XML Analyst to
analyse XML data feeds I soon became responsible for the aggregation of all
news/content feeds into the eGrail content management database.
Content is provided by companies such as
Reuters, iSyndicate, Primagames, ICL, BDS, 365, Softonic, Met Office, Press
Association and various music companies. Each one uses a different format and
different providers used different methods of supply either push (FTP), pull
(client) or email.
I designed and implemented a B2B application
called Stagecoach. Stagecoach accepts content in any format: XML, HTML, XHTML,
Flat Files, Database etc and through a series of transforms
(XSLT/Perl/JavaScript) converts it to a common Vizzavi internal format ready
for loading into the eGrail Oracle database. Some user facing applications
could use XML directly and for these Stagecoach bypassed the database and
provided XML/HTML/WML directly to them or as static pages to the front end. As
we were up against the usual deadlines and the constraints of eGrail it was
written mostly in Perl but used the Java based XT and Saxon XSLT processors in
the pipeline and MSXSL on the client.
Monitoring and logging are provided by the
Stagecoach web based intranet interface. It provides up to the minute
statistics such as last received time, expired feeds, feeds with errors and
remedial actions. At all stages content/logs can be viewed via a browser using
client-side XSLT transforms to provide an easily viewable representation of the
content.
Other tasks include documentation, working
closely with Java/Perl application programmers to provide XML/XSLT solutions,
knowledge transfer of technologies like XML, XSLT and B2B solutions etc to
permanent and contract staff.
Technologies Used: XML/XSLT, XML Schemas,
JavaScript, Perl, HTML/XHTML/WML, HTC, Behaviours, Java, Oracle, BizTalk, RSS
OAG Worldwide provides timetables of anything
from tide tables to airline/airport flight timetables.
My job was to produce a set of multilingual
templates that could be seamlessly slotted into a customers website. These
covered various initial flight selection pages where destination, date and
preferred airline could be selected, through pages displaying flight summary
and flight details information. These are cross browser compatible, reasonably
dynamic and fallback gracefully on older browsers.
The system is an n-tier architecture
comprising SQL Server, TSQL, VB business objects (MTS) and ASP for
presentation. The ASP code queried the middle layers ("Flight
Engine") using XML and received an XML response which was formatted to
create the summary and details screens. Although I was working mainly on the presentation
layer I also wrote VB COM objects for doing city/airline lookups on the
database which were delivered to the client utilising Remote Scripting.
Other tasks included documentation,
implementation of source control measures and knowledge transfer of
technologies like VBScript, JavaScript, XSLT, COM and n-tier solutions etc to
permanent and contract staff.
Technologies Used: XML/XSLT,
HTML/DHTML/XHTML, JavaScript, HTC, SQL Server, TSQL, MTS, VB COM, VSS
I worked in many areas at Genie. Initially on
the voucher system for free phone time on new WAP phones. I later wrote a
Visual Basic application to concatenate and upload to the web new vouchers.
I then worked on the customer care
application using Perl on Apache with HNS from ALD. The application was to
allow customer care representatives to repair and update users details in the
Informix database, stop and start SMS messages to mobile phones and change
passwords etc.
I also worked on site statistics using Web
Trends, IIS, SQL Server 7, ASP, XML, VBScript and JavaScript. I wrote scripts
to download zipped log files from the Apache server to the NT box for
processing by Web Trends. Then wrote marketing facing web pages that displayed
table of contents of Web Trends data. I wrote ASP pages to interrogate the SQL
Server 7 database and display graphs for data not covered by Web Trends.
I also did some upsizing of access databases
to SQL Server 7 for the time management system.
Technologies Used: XML/XSLT, HTML/DHTML, HTC,
ASP, VBScript, JavaScript, SQL Server, TSQL
I was working on an internal website for
organizing the ICL knowledge base. ICL needed a cohesive front-end and
framework to pull together all documents (Word, PDF, Excel, HTML, ASP, XML,
PowerPoint etc) from different departments/communities and link these together
with tools, utilities and dynamic data sources to form a digital dashboard. XML
was used extensively for document details and attributes, either as static
files or via SiteServer ASP scripts. I developed the system mainly using XML
and DHTML using ASP and Perl as the glue.
The front-end had to be very flexible and
customizable for each user and each community. This was achieved using XML/XSL
on the server and CSS and XML/XSL on the client to display individual table of
contents, voting sections and news reports. Because this is an intranet we only
had to support Internet Explorer which made life easier although both v4 and v5
had to be supported. The power of XML/XSL allowed a small number of files to
control the look and feel of thousands which made maintenance a simple task.
Although the initial development was to
produce an English only version care was taken to allow for multi-lingual and
localized views for the European branches of ICL.
I also did some work on LDAP and directory
services and worked on defining part of the ICL vocabulary.
Technologies Used: XML/XSLT, XML Schemas
HTML/DHTML, JavaScript, ASP, Perl, LDAP, VSS
The Exchange is a company that provides
support for the insurance industry and Independent Financial Advisers. I was
working on the eXweb Intranet and specifically the Document Library and
Maintenance functionality. This provides for the uploading and downloading of
all documents relating to providers? products and the maintenance of document
details and versioning. The final product was deployed on SiteServer and made
use of the SiteServer User Object and security. I used VisualInterdev 6 to
implement HTML, DHTML, DHTML Scriptlets/Server Scriptlets, JavaScript,
VBScript, XML, VB and various ActiveX controls. Document details are held on
SQL Server and manipulated using stored procedures. Documents are mainly in PDF
format but compound PDF/OCX files are also supported. I also gave support to
other VB developers new to the Internet and DHTML.
Technologies Used: VB, XML/XSLT, HTML/DHTML,
SiteServer, COM+, SQL Server, TSQL, VSS
SoftAd is a software house developing a
product called Focal Point for the Ford Motor Co. Focal Point is web based
sales support product for use in Ford Dealerships. It uses ASP and IIS4 to
dynamically build web pages from data held in a Microsoft SQL Server database
and data held on a Ford Corporate Server. Local data is accessed mainly through
stored procedures in SQL Server and is used to create dynamic pages based on
the model, year, colour and finance package. Due to the global nature of the
project all pages have dynamic multi-lingual support.
SoftAd is working closely with Microsoft to
develop a newer version based on Microsoft Transaction Server and Message Queue
to enable a more distributed solution based on server farms.
While here I have worked extensively with
ASP, XML, HTML, DHTML, SQL, VbScript, JavaScript, Perl and ActiveX which have
all been used to integrate the final solution.
Technologies Used: XML/XSLT, ASP, SQL Server,
TSQL, HTML/DHTML, COM+, MTS, MQ, VSS
I was employed at Lilly to complete work on a
web-based purchase to pay system written in JavaScript and Perl. As it is to be
used all over Europe the interface is multilingual. It is designed to take the
user through a series of steps necessary to complete the purchase and payment
for goods. Information is stored in an Oracle database and accessed via ODBC.
Perl scripts build up the web pages to provide selections and options based on
previous responses in the process. Form validation is done both at the front
end and the back end. The different languages are catered for by replacing
English text with foreign text as the pages are being built.
Technologies Used: Perl, JavaScript, Oracle
I was employed at B.T. to write provisioning
software for their OMS system. Most of the work was in c and embedded SQL
(Oracle). I initially worked on the Featureline team and as it was the end of
the project work mostly included fixing coding bugs and system testing.
I then worked on the Home Highway
implementation and am writing the low level SystemX communication routines.
Technologies Used: C, Oracle, ASN.1
I was initially employed at SEMA as a CMS
librarian coordinating and controlling all software being developed for the
Hutchinson CABS 2000 project team. This was a monumental task and it soon
became clear that some kind of CMS front end was needed to handle all of the
different releases that were needed. I developed a menu driven CMS front end
handling multiple libraries. This was later improved to handle different
projects requirements and is planned to be the standard CMS interface for all
CABS 2000 projects.
I also did some work on process to process
communications for the data capture part of CABS and some C programming with
embedded SQL.
Technologies Used: CMS/MMS, C, SQL
Swift Terminal Services provided software and
hardware solutions for connection to the Swift network. As an OEM they worked
very closely with DEC and almost no expense was spared to provide every DEC
product.
My initial task was to work on the conversion
of Swift messages to ST400 internal format for V2.5. The syntax parsing engine
was originally written very badly in Basic and needed to be rewritten in C and
all database accesses needed to be made async to improve performance. As this was
the major bottleneck of the ST400 system I was involved in the optimization of
all other subsystems which impacted on Swift to Internal.
St400 was written mainly in Basic with some
low level routines written in Bliss32 and Macro32, so keeping data structures
aligned was a major headache. With the introduction of C we decided to use SDL
for the definition of all data structures on the system. I implemented
automatic build procedures (CMS/MMS) and rationalized/optimized datastructures
(SDL). This effort was not wasted when we came to integrate Swift l (V2.5) and
Swift ll (V3.1) into (V3.6) which up to this point had followed separate
development paths.
I later moved onto the Enhanced Telex400
project where I wrote the new telex editor using callable TPU. Created new
build and installation procedures for Enhanced Telex400, Traffic400, Report400
and Extract400.
I set up procedures for automatic generation
of documentation (VAX Document) from source code to create on-line
documentation available to all developers through Bookreader.
I wrote programs to rebuild and repair the
Swift and Telex customer information files. I wrote new programs to handle
events and journaling and standardize event messages and codes.
I provided technical support to other
developers and 2nd or 3rd line support for field problems coming from the help
desk. I implemented encryption algorithms for V4.0.
Technologies Used: C, System Routines,
Systems Services, SDL, CMS/MMS, VAX Document, ST400, French
This was a contract to write a device driver
for the new version of MIRA or HAMS (High Availability Management System) using
the new KWV32 board. HAMS runs on a 3000 series dual host system providing
shadowing, error monitoring and failover functions for highly critical
applications. Most customers include banks where it is important to have the
systems available at all times. Although it is not a fully fault tolerant system
it goes a long way towards it. The KWV32 is a modified DSV11 including a 68000
processor with new functions included in the firmware to monitor the link, the
remote system and the driver. I was involved in the top level design and
writing the driver in Bliss32. I also became involved in debugging the firmware
and providing technical support for the higher level software.
Technologies Used: Bliss32, Firmware, VAX
Document, French
Walmore Electronics is a defense company who
were writing radar training simulators on VAX and PCs using ADA C and Macro32.
My tasks included writing a device driver, writing programs to control serial
interfaces and technical support for the development team. The device driver
controls a DRV11-J parallel interface card connected to a dedicated device
which simulates audio and visual radar displays. The driver uses two of the 16
bit ports to create a 32 bit parallel output port. I/O is synchronized using
device ready and device acknowledge lines. The driver has sense mode and set
mode functionality, can return diagnostic information and makes use of the VMS
error logging facilities The serial interface procedures are used to connect
the VAX to the PC network via RS232 lines. Technical support was required as
the team had little or no VAX experience. Other tasks included installation of
new software releases, installation and support of DECNET and other usual
system manager functions.
Technologies Used: C, DECNET
APAK is a software house who have dealt
mainly with the Canadian computer system GEAC. They have various clients who
due to GEAC's financial difficulties wish to transfer their operations to DEC
equipment. Their major client when I joined was Barclays Mercantile Highland
Finance a leasing company based in Borehamwood. Neither APAK or BMHF had any
in-house VAX experience and I was taken on to provide technical support
analysis and programming skills for the VAX side of the project. The solution
was to use Real-time software to cross compile ZOPL into MACRO32 for execution
on the VAX. APAK however have their own languages and applications KARL and
PEARL which sit on top of ZOPL and use GEAC facilities not available or used
differently on the VAX. My duties include analyses and writing software to
mimic GEAC system functions such as Locking routines, Terminal emulation,
Global section interfacing, Communications interfaces and File handling
routines. We needed Nontransparent communications over DECNET, PSI (x25 and
x29) using PSS and ISTEL networks over a Kilostream link and Lat over an
Ethernet link. All PC systems were connected to the VAX over networks for
interactive sessions and file serving. I wrote various multi-threaded programs
for file serving over DECNET to access remote databases using AST's and other
synchronization techniques and for Soft locking of files which were accessed
using QIO to the ACP instead of RMS. Most of the time I was working on Client's
sites and gained great experience in handling customers and their problems.
Using this knowledge to directly influence the direction of the project.
Technologies Used: C, DECNET
This contract was initially for 2 months to
write Change Control Procedures and set up Access Control on the VAX cluster.
Barclays had just been audited and the auditors wanted to see a smooth and
secure method of applying new and updated releases of software to the live
system. They also wanted to see a more strict and policed environment for the
users with access to live data. Change Control was accomplished by writing DCL
procedures to transfer files from a development handover area to a pre live
area before release. All files were compared with their live equivalents before
compilation. The compilation section had to take into account all forms of
source file and allow for the inclusion of new compilers. The procedures had to
take into account 4gls which are interpreted rather than compiled. Compiled
sources (objects) had to be added to the correct object text help or forms
libraries which were copied back from the live environment to avoid invalid
updating of live software. As many of these actions produced files which were
needed for the release a database had to be set up to keep track of the
necessary files. The whole system was menu driven to necessitate as little
operator input as possible. Access control was set up using ACLs and the Rights
Database to restrict access to live files by the development teams and other
groups of users. I wrote some DCL command procedures to update the ACLs and
create new ACEs. This was necessary because doing it via the ACL editor or
manually would have taken to long. These were also fully menu driven. This all
required a great deal of documentation to comply with the auditors requirements
and I wrote a 90 page manual on the Change Control / Access Control procedures
and operator / user instructions.
Technologies Used: DCL, CMS/MMS
This was a short contract to write a fault
tolerant datafeed handler for telerate. The process is based around the
MicroVAX using DECNET communication and SOP modems. The project was written in
'C' and used many VMS System services (async QIO, timer, mailboxes), AST code
and event flags.
Technologies Used: C, System Services, DECNET
I was employed at CSFB to design and write a
real-time multi-threaded (up to 16) output spooler for the link between the VAX
and the Beeline telex system as part of an Allin1 telex subsystem. I used Macro
32, Fortran and the VMS symbiont routines. Initially I was working on only the
spooler but also took on modifications to the editor and in time became
responsible for all parts of the project. The system made full use of global
sections, system locks, the Job controller/Queue manager interface, driver
level code and routines, RMS and many system security and backup functions.

Langton had a support contract for the Xerox
Integrated Composition System (XICS) covering the UK and Europe. They also had
their own suit of products to support XICS. The majority of these systems were
based in IBM kit but they were recommending the VAX as a low cost alternative
for the smaller companies. This required the development of VMS specific
software and the integration of LEPS products into the VMS environment. We did
this by designing and writing a screen based data entry system using the VMS
screen management and run time library routines to mimic FMS and ISPF. Langton
got an OEM contract for the Imagitex image scanner which was connected to the
VAX via a DR11-W. Because of my experience in communications between the VAX
and other hardware including the ICL Perq, IBM PC and 370 using 2780-3780 and
APS 5 photo typesetter I was sent on a DEC Macro 32 and device drivers course.
I then wrote a device driver for the DR11-W. I was then transferred to the
Electronic Warehouse team which was developing a product for demand publishing
of graphics and documents based on Langtons Artwork Manager product and gained
experience in Iftran, IBM CMS TSO and ISPF.
Technologies Used: Macro 32, Fortran, XICS
Our department offered a service to users
doing software development, real-time simulations, trials analysis and CAD/CAM.
I joined Marconi just after their decision to transfer from GEC 4082s to VAX
11/780. I was responsible for training the other operators and system
programmers in the use of DCL and the VMS operating system. I worked closely
with the system programmers and in March 1984 was promoted to system
programmer. Projects I have worked on include system design and configuration,
operating and system analysis, software installation and tuning. I attended a
DEC course on programming VMS in Fortran 77 in the summer of 1983 and gained a
full knowledge of structured Fortran its libraries, system service calls and
runtime libraries. I also have experience in the installation of DEC and other
software; DEC and other hardware and communication between them. My programming
experience includes Calcomp emulation on a 4115B using Fortran and Macro 32;
archiving programs; control of the issuing and plotting of files and update of
the associated tape and document libraries; reformatting floppy disks from VMS
files 11 to RCA Cosmac format and stock control using a menu program with full
screen graphics. When I left I was working on a suite of programs to extract
information from the system accounts file and produce reports and graphs of
system usage and performance.
Technologies Used: Fortran, Macro32, DCL,
System Services
Schlumberger London is a log interpretation
center for the oil industry. Engineers working in the field gather information
and data from oil wells and transmit it to one of the Schlumberger centers for
plots and maps to be made. These are then sent back to the rigs to enable
drilling to continue. Because of the nature of the work I was often working to
deadlines and work had to be of a high standard. The work included a lot of
transmission work via BT modems, plotting using various Schlumberger specific,
Versatec and Calcomp plotters, archiving stock control and running user programs.
