Team Lead, Senior UI Engineer and JavaScript Expert
I have 13+ years application development experience, 7+ years focused on front-end single-page applications development, enterprise integration, and service oriented architecture. And the last 5 years - a Technical Team Lead. I worked as a contractor for companies like BuzzFeed, Adidas, Hewlett Packard, and Pearson.

I am a JavaScript expert and focus on building complex single-page applications. Code the most valuable asset, and it is better to do it right from the beginning. I like feeling proud about work I have done, and I highly value my reputation as a great products developer.
