What I'm looking for

I seek frontend roles at product or outsourcing companies in Poland/EU where I can improve performance, build responsive UX, and collaborate across product, design, and backend teams.

I am a frontend developer with 4+ years building scalable web applications using React, Next.js, and TypeScript, focused on high-performance, responsive user interfaces and strong UX.

I have reduced runtime errors by adopting TypeScript, improved load speed through refactoring, and delivered analytics and visualization features using echarts.js, D3.js and Leaflet that led to client growth.

I collaborate closely with product, design, and backend teams, value mobile-first responsive design and performance optimization, and am open to opportunities with product and outsourcing companies in Poland and the EU.
