Top SchoolKarol Mocniak is a senior software engineer based in Warsaw with 10 years of experience building and modernizing web platforms and microservices. He has led architectural reengineering efforts and helped reorganize teams into product-oriented units while introducing CI/CD and developer workshops. His background spans PHP/Symfony ecosystems, Docker/Kubernetes deployments, and turning legacy monoliths into independent components for companies like GOG.com, ClickMeeting and Instapage. Colleagues know him for mentoring developers and running coding dojos as much as for pragmatic, hands-on implementation. He blends practical engineering with a dry sense of humor and a knack for keeping projects moving through messy organizational dynamics. Despite a cheeky public persona, his track record shows steady delivery of scalable, maintainable systems.
