I'm a software developer from Thrikkunnapuzha, a village in Alappuzha, Kerala. I've been writing software in many languages for two decades, and C# and .NET have been my main tools for a long time now.
I grew up playing games and tinkering with electronics. GW-BASIC got me into programming, then came assembly, C and VB6.
Now I build AI agents and supervise AI coding agents as they write software. Lately I'm porting the DOS games I grew up with to C#, letting AI do the reverse engineering, and writing the tools that let it see and play them.
