About Me

I am a Frontend Developer with in-depth knowledge of modern frontend programming languages and a good eye for aesthetics in building frontend components, converting existing monolith into reusable components and bridging the gap between design and technical implementation - defining how solutions look and work. I strive to develop and deliver user-friendly, performant interfaces through consistent, high-quality code.
