About me

My name is Kostas Rontogiannis. I received my diploma on Electrical and Computer Engineering from the National Technical University of Athens in 2015.

I specialize in the .NET framework, but also like to tinker with any interesting concept, specially functional languages. I'm also interested in high performance programming including cloud computing, multicore programming, down to garbage collection and JIT compilers.

As a student I was Microsoft Student Partner for several years; lead and co-founded the first offline student community called StudentGuru NTUA focusing on .NET. During this time, I gave several talks about Microsoft related technologies. I've also given a few talks on the Athens F# User Group.
