About

Hi, I’m Michal Katrak, a Senior Front-End Developer focused on React and TypeScript, building scalable UI systems and micro-frontends for enterprise products. I design reusable component libraries and front-end architectures that scale with distributed teams, with a passion for clean code, performance, and delightful user experiences.

I collaborate across product, design, and backend teams in Agile environments, optimize deployment workflows, and advocate for thorough end-to-end testing and regression prevention. When I’m not coding, I enjoy mentoring teammates and exploring new front-end patterns to boost productivity and product quality.
