Highly experienced Front-end/JavaScript developer with profound experience in E-learning, Entertainment apps and Finance websites.
I'm ingenious and result-driven Front-end/JavaScript developer with 3+ years of experience. I've been developing beautiful interfaces for websites and progressive web apps for E-learning, Security&Safety, Entertainment, Financial industries, etc. Also, I persuasively simplified a too complex user interface of a huge E-learning platform, while preserving all functionality and redesigned it according to the customer's desires. Currently, I am deeply involved in learning and practicing React.js.

Please, note, that along with hiring me, you'll also get a QA and PM management absolutely free of charge:)
