Wioletta Gluza

Frontend Engineer - building AI products

About Me

Hello, I’m Wioletta - a frontend engineer with 6+ years of experience building accessible, user-focused web applications with React and TypeScript.

I enjoy working at the intersection of engineering, design, and product - creating interfaces that are thoughtful, consistent, and easy to use. Throughout my career, I’ve worked on AI applications, design systems, experimentation, and products used by businesses and users across different markets.

I care about writing clean, maintainable code and building frontend foundations that make products easier to evolve - not only for users, but also for the teams who continue developing them.

Always happy to chat about frontend engineering, AI products, thoughtful UX, or making things better.
