Full stack Software Developer

Merefa, Ukraine



What's the difference

I started programming for Spectrum somewhere in mid school and quickly realized it's a thing of my life. Living off software development since 1998, from spaghetti PHP to Ruby on Rails to Meteor.js I've carefully selected my stack of choice. I'm a Polymer and Material Design adept, when it comes to UI. Docker, Fleet, CoreOS and friends are my loved operational tools. I'm a patient, confident and cooperative team player.
