About the Author

Iain Clarke, Warrior Programmer
Software Developer (Senior)
Sweden Sweden
I have now moved to Sweden for love, and recently married a lovely Swede.

I started programming on BBC micros (6502) when I was six and never quite stopped even while I was supposed to be studying physics and uni.

I've been working for ~13 years writing software for machine control and data analysis. I now work on financial transaction transformation software, for a Software company in Gamlastan, Stockholm.
Look at my articles to see my excellent coding skills. I'm modest too!
