About me

Passion for creating

For over 5 years I've been building web applications that combine modern design with solid backend. I specialize in the React and Node.js ecosystem, but I'm not afraid of new technologies.

I treat every project as my own - I care about code quality, performance and user experience. I believe that good software is one that solves real problems.
