Rockstar🎓
Top SchoolSergiusz Dziekiewicz is a seasoned full-stack developer and engineering leader based in Warsaw with 10 years of experience building scalable web applications and front-end architectures. As Frontend Team Lead at Everhour he drives Angular-based architecture and makes key technical and process decisions while still contributing as a senior engineer across the stack (React, Node/NestJS). His tech breadth spans JavaScript/TypeScript, Redux, ESLint, and databases from MySQL/Postgres to MongoDB, paired with practical DevOps skills in Docker, Nginx and Ubuntu on DigitalOcean. Earlier roles show hands-on experience with data visualization (D3.js), unit testing, and configuration management, evidencing a strong emphasis on reliability and maintainability. Unusually for a senior engineer, he also applies leadership and coaching off the keyboard as a football coach, bringing teamwork and strategic thinking from the pitch into product and people management. He blends pragmatic engineering with people-first leadership, consistently turning complex requirements into maintainable delivery.
