Head Of Development at The Interaction Design Foundation
Warsaw, Masovian Voivodeship, Poland
Summary
🤩
RockstarAliaksandr Lapatsin is a pragmatic Head of Development with 11+ years building and scaling web and mobile products using a web stack, specializing in PHP (Laravel) and modern JavaScript/TypeScript (Vue). He leads small engineering teams (4–7) at the Interaction Design Foundation, driving architecture, CI/CD automation, performance gains (notably a 280% LCP improvement), and developer experience improvements that materially speed delivery. A contributor to high-profile open-source projects like vimeo/psalm, he brings security-minded static analysis and type-safety improvements to production codebases. He’s obsessed with performance, automation, and code quality—often trading small design tweaks for outsized development time savings. Equally comfortable diving into product details or shaping hiring, onboarding and knowledge management, he balances hands-on engineering with cultivating a strong team culture and sustainable practices.
