About me
I've designed and implemented several applications in Erlang from scratch, I know how Erlang works and what it is all about (including Erlang deficiencies), and enjoy applying this knowledge to solve real-world problems. I tend to design complete deployable solutions based on containers (docker mostly), and did quite a few projects already.
I do prefer to develop in a functional style, and I have a keen interest in writing software better with the latest CS achievements (applications of and advances in category and type theories).
I live in Prague, Czech Republic, have European permanent residency permit and Russian citizenship, speak english fluently and some czech. Projects
