I've been working with JavaScript for the past 5 years, last 3 years as a full-time freelancer.
I manly focus on Ember and React on the front-end and node.js (Express) on the back-end.
I am experienced at writing well-designed, testable and efficient code using current best practices. I am hard-working and responsible person, able to work by myself or in a team.
I've also lead development teams in the past.
I am familiar with elasticsearch, redis and different NoSQL(Mongo, Firebase, Rethink) and SQL databases. I also have experience with docker, nginx and maintaining cloud servers (Google Compute Engine, AWS)
