About

I'm a Senior Frontend & Mobile Engineer focused on building scalable product experiences and frontend architectures for complex enterprise applications.

Over the last years I've worked on shared component libraries, design systems, internal tools, and customer-facing products built with React, Angular, TypeScript, and hybrid mobile stacks.

I care deeply about building maintainable UI systems with a strong attention to detail, helping teams move faster while keeping product quality, consistency, and scalability high.

Outside of coding, I enjoy learning, working out, and traveling.
