Skills - Jobs

The title "Software Engineer" suits me best. I get involved in most aspects of systems development from initial design through to installation and ongoing support.

Career History

I have designed an RTSP Gateway for Alcatel-Lucent"s Open Video Server (OVS). The gateway implements the Realtime Streaming Protocol (RTSP) for controlling Video-on-Demand (VOD) playbacks on IPTV networks. The gateway supports over 25000 simulataneous sessions and over 50000 simultaneous connections. I achieved this high connectivity using the Java NIO and concurrency classes.

I developed a prototype video cache to demonstrate how such a product might operate using MySQL, Squid, Apache and Jetty.

In November 1995 I joined the Chots project at ICL in Basingstoke. I specified enhancements to the subsystem that manages graphical workstations over an OSLAN network. I then worked on the design and coding.

I went on to design a system that configured the networking software of all systems on the network. The configurations were controlled from central servers. I went on to do some of the coding which was almost complete when the project was cancelled due to requirement changes.

Skills

ICL DRS6000, ICL SuperServer, ICL TeamServer, Unix ES+, C, sh, XTI, OSLAN, OSI, RFS, make ICL planned to develop mediation system based on newer technology designed by another group. I joined the SIMS team in September 1992 and developed three subsystems around the ICL FTAM product.

In January 1993, I was appointed Design Authority to help sort out SIMS design problems. I was in this position for the first two deliveries.

By April 1994 I was responsible for most of the networking subsystems in mediation systems. This included: software for communicating with System X, AXE10, TXE4E and UXD5B exchanges using bespoke protocols over X.25, software for managing the transfer of files using FTP and FTAM, software for managing MegaPACs, DRS network configurations and MegaPAC configurations. Towards the end of this contract most of this work was enhancing the system.

I joined the DDC project in April 1991. The DDC is a mediation system, it collects billing and other data from System X, AXE10 and TXE4E exchanges. It then passes the collected data to other systems for processing.

My first job was to integrate the ICL FTAM product into the existing DDC. Most of the design work had been done. I had to complete the design and implement it.

I designed the enhancements for DDC Phase 6. This moved some of the networking functions from System 25s to Satelcom MegaPACs. I coded and tested the MegaPAC Management programs. When the development had been completed, I went on to lead one of the installation teams.

Skills

Unix SVR4, C, Informix, SQL, ESQL, make, sed, awk, ksh, MegaPAC, MegaWatch, OSLAN, XTI, FTAM, DRS6000, ISO Transport, OSI, Design, Programming, Installation, Validation, Support. Most of my time at Unisys was spent preparing proposals for various customers throughout Europe. Typically these would involve some form of computer network. My job was to prepare the technical content of the proposal after determining the customer's requirement.

I worked on a project for Unisys marketing to determine the requirement for a Software Distribution package. My proposals were accepted and I started up the project as project manager.

Skills

Unix, C, MS-DOS, U6000, X.25, LAP, LAP-B, Software Distribution, XTI, X.25, BS5750, Project Management, Design, Support, Validation, Market Reseqrch, Quallity Audit. At Carnell I was involved in a number of projects. Typically, these included either communications or security software. In many cases, I was involved from requirements through to installation and support.

My first task was to design some Unisys and IBM terminal emulators for DRS300, CDOS systems.

In November 1987 I started the design of an access control system for a major defence system. This allows access to a DRS300 system only after the user has been authenticated by a central mainframe. I went on to lead the development through to delivery.

I designed and developed a terminal emulation environment for Unix systems, UniView. The first version supported Videotex and ANSI terminal emulations on DRS300 and DRS400. I also worked on some enhancements such as a UniView API and connections to different network types.

Other projects included the development of a terminal emulator for connecting to System 25s, the screen handler for a Reuters Monitor. I also wrote a down-loader for a Hand-held terminal and other security products.

I was responsible for the network management software at ICL INS. INS provided the network for Tradanet and the National Bingo Game.

Some of the network management software was bought in, which I supported, enhanced and modified to suit our requirement. I also designed and implemented the connection management protocols and software.

Skills

VAX, C, Unix 5.3 Kernel, Sockets, make, sed, awk, grep, Network Management, Design, Protocol Design, Programming, Support. I was introduced to Unix and C when I joined the Esprit ROSE project. A consortium of European computer companies implemented OSI protocols in Unix Systems.

On joining, I helped complete the development of the transport service.

I designed the ROSE implementation of FTAM. I went on to lead the development team and program some of the FTAM and Presentation modules.

Skills

Unix Kernel, C, make, OSI Transport, FTAM, ASN.1, PERQ, CLAN, Design, Programming, Project Leadership. I joined the Osnet support team at the end of '82. Osnet was a new product at the time. It provided access to ethernet LANs to systems using other protocols.

I did most things that could be considered 'support'. This includes fixing bugs, product testing and network design. I also ran two field test sites and supported what was believed to be the largest LAN in Europe at Queen's University, Belfast.

Skills

Ungermann-Bass NIU, OSLAN, Osnet, Pascal, ICLC-03, Network Design, Support, Validation. I joined a team developing software for the ICL 1500. This transferred BACS magnetic tape files from the 1500 to a VME mainframe. Later, I modified this code to receive the files and write them to tape. This replaced the mainframe software.

In 1980, I was seconded to ICL South Africa to work on the software for a network of ICL 1500 systems for a large retail chain. These systems connected to a VME mainframe using the ICLC-03 protocol. I developed the file transfer and the print spooling software. When the development had finished, I stayed on to support the customer during rollout.

I wrote a few other systems on the 1500 and also modified a terminal emulator on an ICL 7500.
