John Purcell
Software Development Trainer

After working as a software developer and contractor for over 14 years for a whole bunch of companies including CSC, Proquest, SPSS and AT&T in the UK and Netherlands, I decided to work full-time as a private software trainer. I now live in the beautiful city of Budapest, Hungary, from where I run the website Cave of Programming.
