Summer 2000 Venners PLC. Development of a computerised system for work planning that finds the most efficient combination of jobs for each auditor each week based on the distance by road to the job and the required skills. Work also involved re-writing the DOS based invoice system as a Windows 2000 program and the development of a distributed parallel system for indexing the distance, time, cost and route by road between all auditors and all jobs in the UK. A large amount of experience was gained in C, Visual Basic 6 and Microsoft SQL Server 7.
Summer 1999 Deloitte and Touche, National Assurance and Advisory Department. Y2K compliance testing of in-house audit software, complete overhaul of departmental intranet and the design, writing and testing of a number of computer tools to simplify a range of previously very labour intensive tasks.
1998 - 2000 Imperial College of Science, Technology and Medicine. Chemical Resource Discovery and Teaching project manager. The initial aim was to produce a CDROM with copies of all undergraduate chemistry lecture notes and past exam papers as well as copies of free chemistry related software that would be distributed to all IC chemistry undergraduates at the start of the 1998/99 academic year. This aim was successfully achieved and further work involved improving and updating the project for a further 2 years in succession.
