Summary
👤
Senior🎓
Top SchoolJiří Kubala is a seasoned Frontend Engineer with two decades of web development experience and nine years focused on modern frontend stacks like React, TypeScript, and design systems. He started in the era of PSD-to-HTML and IE6 quirks and evolved into building high-performance, accessible UI components—most notably a self-built React Table with virtual rendering capable of displaying millions of cells. Jiří specializes in developer experience, scalability, and web accessibility, delivering component libraries used by large internal teams and integrating them into enterprise applications. He pairs hands-on implementation skills (Storybook, Cypress, Jest) with backend-aware optimizations from his PHP and full-stack freelancing background, and he’s actively exploring AI-driven frontend patterns and chatbots to push UI architecture forward.
