Technical Experience:

2002 -. Web site development for well-known rock & roll band

2002 - Video camera capture device driver for BSD

2002 - . Telecomms consultant to [snip] Loughborough, advising on aspects of ISDN and SS7 implementation.

2001 -. Design, integration and validation of several new features in a voice and DTMF processing system using [snip] DSP56K3 processors. Work involved designing software to implement G711, G726 and G729 protocols from ITU-T Recommendations and testing in Passport Exchange equipment utilising VoIP.

2000 -. Fixed price contract to convert an existing C-ISAM configuration data-base to Informix ESQL-C, with corresponding adaptions for the maintenance utilities and user interface.

2000 -. Fixed price contract to port a major telecommunications software product to a new architecture and operating system. The system makes extensive use of TCP/IP network protocols and supports both ISDN and SS7 switching technologies with multilingual grammar support for voice response units. The system offers full call control via a graphical drag-and-drop GUI based on X11 graphics.

2000 -. Fixed price contract to merge two branches of a major telecommunications software product (circa 4,500 files), port the resulting common code to four platform architectures (HPUX, NSUX, Proliant XC and NSK), and test the ported code on all four platforms.

1998 - 2000. Development, enhancement and third-line support of a large software suite implementing telephone switching controls and services for SS7 and ISDN subscriber systems. The system implements facilities such as pre-paid mobile, enquiry systems, automatic answering and call forwarding. The system is available on Unix (HP9000, SGI, Tandem S4000 and XC) and Tandem S7000 NSK platforms

1998. Project planning, requirements analyses, technology evaluation, specifications and design descriptions for an embedded controller for a Band III digital audio broadcast controller.

1993 - 1998. Technical director of [snip]. Real-time software and hardware consultancy and design and development services for several clients. Clients include [snip]

1993 - present (intermittently). Design, implementation and maintenance of Company Intranet and Internet service, providing email, web access, Company database and web-site facilities. The services use integrated BSD and NT4 servers internally, with dial-on-demand access to an external Internet service provider. The Intranet has NT4 and W95 clients accessing shared and private data on both Unix and NT servers, and using shared networked printers and plotters. The service uses applications and web pages written in compiled C, HTML, CGI scripts in bash shell and Perl5, Java-based applets, and Adobe pdf.
