I currently specialize in building websites for small and medium business owners.

General: RubyOnRails, PostgreSQL, MongoDB, RSpec;

Other stuff: Linux, GraphiQL, Git, NodeJS;

If I'll try to list everything here it will be a very long list. So these are enough to illustrate the sphere of my expertise.

If you are looking for a serious and capable programmer, then you look no further.

That's all. Thanks for reading. If you have any questions or proposals - feel free to contact me and we'll discuss it in detail.
