Yuri has both back-end and front-end experience. He cares a lot about design although he's not a designer; he's proud to walk all the extra miles to get a pixel-perfect layout and the most consistent API. He has worked as a team leader and as a team member and has done very well in both roles.



Preferred Environment

Git, Atom, MacOS

The most amazing...

...things I've created are an algorithm to make two colors combine and the application of a sigmoid function to make comparisons with an equality operator.
