Senior🎓
Top SchoolAndrzej Ziółek is a Lead Frontend Engineer and delivery-focused tech leader with 8 years of experience building production-grade web applications and steering cross-functional teams from startup task forces to corporate environments. He architects and ships complex frontends—most recently the UI for Octant, a Web3 platform integrating data from smart contracts, Subgraph, REST APIs and multiple microservices—while also owning delivery, testing, and team growth. Equally at home in hands-on TypeScript/React work as in recruitment, roadmap creation and scrum adoption, he scaled a team 2.5x in 14 months and introduced robust E2E testing for time-dependent workflows. A perfectionist by nature and pragmatic in execution, he combines a pixel-perfect, data-driven approach with system-level thinking rooted in a mechatronics engineering background. Outside work he channels a racing-driver mindset into relentless optimization and continuous improvement.
