I have been working as a computer professional since 1983 on projects ranging in size from one person to multi-million pounds. In that time I have worked as programmer, analyst, project manager and trainer.
I first saw a spreadsheet in 1985, before it was possible to select cells with a mouse!
I have been using spreadsheets (both Excel and Lotus) in my work since 1992.
In 1997, I was asked to convert high-level engineering spreadsheets when the organization moved from Lotus 123 to Excel.
Since that date I have been developing complex spreadsheets and using them to solve problems for many clients.
