Leslie joined ECC as Technical Director from Systemcare in July 1990 and brought with him a very high level of in-depth expertise, including the unusual combination of operating environment and software design technology. Leslie is responsible for the long-term technical direction of ECC and the technical strategy of all of its customers, identifying potentially important skill sets and technologies and ensuring that company knowledge levels are able to exploit current and future opportunities. Avoiding certain technologies can be just as important as adopting others, and there is no doubt that careful strategic decisions have made a key contribution to the company's success.

Despite being technically oriented, Leslie has considerable business experience allowing him to identify means of using technology efficiently, as well as understanding the opportunities it offers and the design solutions needed to exploit these. An example of this was the Bodycote plc GOLD System – e-Business in Action.

Educated in Computer Science and Mathematics, Leslie won an award from Sunderland Polytechnic in 1988 for the fastest ever attainment of a part-time degree (three years) whilst working full time in the R&D Software Department of Courtaulds plc.

As well as being a technoholic (studying vigorously all new devices, tools and concepts as they appear), Leslie is a passionate motorcycling enthusiast and the proud owner of a Ducati 996 which carries him on his annual pilgrimage to the Isle of Man.
