I'm a software developer interested in Python, C#, C++, Rust, JavaScript (both server side and client side), HTML5 (WebSockets mostly) and more. I'm very interested in scalability and caching problems especially in the context of TCP (or even UDP). On the other hand some low level programming (e.g. machine code) excites me as well.
I do like databases, mostly SQL. I'm yet to be convinced that NoSQL is useful. :)
I also like to spend my free time on advanced mathematics. Especially algebraic topology.
