I discovered C# and .NET 1.0 Beta 1 in late 2000 and loved them immediately.
I have been writing software professionally in C# ever since

In real life, I have spent 3 years travelling abroad,
I have held a UK Private Pilots Licence for 20 years,
and I am a PADI Divemaster.

I now live near idyllic Bournemouth in England.

I can work 'virtually' anywhere!
