Summary
👤
Senior🎓
Top SchoolKarol Walasek is a Senior Full-Stack JavaScript Developer with 10 years of experience building and operating production systems, particularly with Node.js, React and Debian-based infrastructure. He combines hands-on development with systems architecture and on-call system administration—managing everything from CI/CD and distributed messaging to Proxmox-backed AI compute clusters. As a former technical lead and co-founder, he has coordinated international teams, run hiring, and taken ownership of product takeovers and post-launch maintenance at CouponFollow. He’s comfortable across the stack and multiple languages, contributes open-source tools from his GitHub, and explores distributed systems, cryptography and blockchain in his spare time. An uncommon strength is his blend of low-level ops expertise (ZFS, vGPU, backup, billing) with product-focused engineering and long-term roadmap planning.
