    Python System/Web Developer

    Russia - Last active: 21 hours ago - Tests: 5 - Portfolio: 3

    Python is my favourite language and I use it for implementing various system utilities and web backends (with Django framework). I am a server-side guy but despite this I also know how client-side (JavaScript, etc.) stuff works. Besides Python I like functional languages: Haskell, Ocaml, Lisp (Scheme) but they are just my hobby.
