About

Hi, I'm Vilizar 👋

I'm a self-taught Front-End Developer originally from Bulgaria, now based in Dunstable, UK.

I started learning to code out of curiosity. What began as online courses and small personal projects gradually became something I wanted to pursue professionally.

Since then, I've focused on React, TypeScript and Next.js, building projects that helped me understand not only how to make interfaces work, but how to structure them clearly, test them and keep the code maintainable as the project grows.

What motivates me most is understanding why a solution works, improving the way I think about software, and continuing to grow toward my first role as part of a real development team.
