A senior Full Stack Developer: React, Node.js, GraphQL, MongoDB

Being a youngster I was inspired by the work of Jordan Walke, who motivated me to become a web developer myself. I chose to major in Computer Science at the uni. By that time I was already developing simple web applications as a freelancer. I boosted my English proficiency thanks to staying in the US for a couple of years. Interned at Facebook. I believe that my contribution to the community and successful projects will tell more about me as a professional than just words.
