Senior Full-Stack Developer: React.js | Node.js | Nest.js | GraphQL | MongoDB |
Being a youngster I was inspired by the work of Jordan Walke, who motivates me to become a web developer myself. Therefore, I chose to major in computer science at the uni. By that time I was already developed simple web applications as a freelancer. I managed to get an internship on Facebook and boost my English proficiency, staying in the USA.
Years of successful experience in both Backend and Frontend expand my skills. Nowadays, I can say that I’m an experienced Web developer, with a solid technical background.

Skillset:
- React.js | Redux | Redux-Saga
- Node.js | Nest.js
- GraphQL | Apollo | Realm
- MySQL | PgSQL | MongoDB
- HTML5 | CSS3 | SASS | LESS | Bootstrap

I believe that my contribution to the community and successful projects will tell more about me as a professional than just words.
