    Ukraine - Last active: 6 days ago - Tests: 4

    I am enthusiast with both commercial and non-commercial experience in IT. My experience includes: * Python (Django, Pylons/Pyramid, Tornado, webpy) web development; * Voluntary support of small-to-mid scale computer networks; * Unix/Linux server administration; * Contributing to various open-source projects; * Fun oriented not-so-mainstream tools (Haskell, Erlang, Forth) self-education. I tend to choose tools suitable for specific problems rather then focus on a single technology. I am available for research on unfamiliar domains and technologies. Learning new things is fun; learning new things for real-world tasks is double fun! I am looking for challenging IT projects which hopefully will save someone's time / provide new opportunities / make the world better.
