Jon Castle

Originally from Sevenoaks, after studying computing at college leaving in 1980 I worked in London for 2 Patent Agents on annuity systems. In 1985 I relocated to Stuttgart, Germany where I was with Ericsson and then Nokia as a programmer in COBOL/Assembler/C creating text-processing, electronic-archiving and document-imaging systems.
In 1996 I returned to the UK and worked for Fidelity and later Prudential on investment banking systems developing in C++/SQL.
Since 2007 I've been working for my own company, Ah Ha!! Software based in a village in Surrey on various web development projects, mainly in PHP.
Apart from all that, my kids have grown up and are now far, far away - but my dog keeps me company and I do a lot of walking, exploring and more than just work!!
