Open Source

I’m not very active open source contributor but I give back when I have something. Over years I’ve contributed to such Open Source projects as GNOME, DataMapper, dm-is-slug, nanoc, Undress, Paperclip, CarrierWave and a number of others. Some of my current open source projects you can see on my GitHub profile.

Also I did a number of commercial projects.

You may want to take a look at my CV (a boring version). And you may want to contact me if you need experienced software engineer for your project.
