    Full Stack Developer

    Russia - Last active: 1 day ago - Tests: 13 - Portfolio: 3

    I'm a web-developer with 6 years of web development experience (4 years experience with PHP, 2 years experience with Node.js). I'm a fluently with spoken English and located in Russia (in Syberia, Omsk, to be exact). But enough about me - I'm more interested in knowing how I can serve you better! Do you have an existing web application that needs someone to jump in and quickly be able to contribute with bug fixes, performance optimizations, or any other type of maintenance? I'm the perfect person to help your app run as smoothly and efficiently as possible. Do you have a plan for a new web app that you need someone to bring to life? We can work closely together to ensure that things are up and running quickly and as you envisioned it. In my spare time outside of working on the computer I travel as much as I possibly can and I'm also studying the Chinese language.
