About Me

I'm a Frontend Engineer focused on building intuitive, maintainable and high-quality digital products.

My work sits at the intersection of engineering, UX and product — from frontend architecture and design systems to backend integration and infrastructure.

My main experience is with TypeScript, React and Angular, with additional experience in Golang, APIs, databases, cloud infrastructure and CI/CD.

I enjoy understanding not only how something should be built, but also how users will experience it.
