Brno, Southeast, Czechia
Summary
👤
Senior🎓
Top SchoolMatej Leško is a Frontend Tech Lead with a decade of experience building high-impact web applications using Svelte, React, and Vue, and transitioning teams from REST to typed GraphQL APIs. He combines hands-on engineering with people leadership—hiring, mentoring, and improving frontend health—having cut app bundle size by 72% and increased automated tests fivefold at a previous employer. As a freelancer and consultant he pairs frontend expertise with middleware and DevOps experience (GraphQL-yoga, AWS, CI/CD) and prefers B2B, part-time contractor engagements. Curious across IT domains, he proactively applies cross-disciplinary skills from backend, testing and product to accelerate delivery and reduce technical risk. Based in Brno, he balances continuous self-improvement and communication skills with practical delivery, and asks for clear, algorithm-free interview processes and competitive contracting terms.
