About Me
Frontend Developer with over 4 years of experience building scalable web applications. I specialize in TypeScript, React, and Next.js, and I enjoy working close to product and design to ship high-quality features.
I have hands-on experience with design systems, and I like turning complex flows into clear, reliable UI modules. I also care a lot about testing—especially E2E automation with Playwright.
In teams, I contribute through code reviews and mentoring, and I focus on making solutions maintainable and easy to iterate on.
Modernization & Refactoring
I modernize codebases (including migrations to React) and refactor towards hooks and maintainable patterns.
Design Systems
I build UI modules on top of design systems and care about consistency, accessibility, and developer experience.
E2E Testing (Playwright)
I can set up an end-to-end testing strategy from scratch to reduce manual QA and support effort.
