Rockstar🎓
Top SchoolPaweł Zarębski is a Python software engineer with a decade of experience building and optimizing large-scale web platforms, currently working at Gcore after leading performance and architecture efforts at Mirumee. He specializes in backend systems, Django and FastAPI, profiling and tuning with tools like cProfile, Datadog and SQL EXPLAIN, and has hands-on experience refactoring monoliths, designing event-driven systems and shipping data migrations for millions of records without downtime. A contributor to the popular Saleor ecommerce core, he’s improved checkout and order logic and streamlined image and user avatar handling to boost consistency and reliability. Passionate about algorithms, metaprogramming and idiomatic, DRY code, he applies KISS principles while embracing modern Python tooling such as mypy, pytest and poetry. Comfortable across the stack from APIs to GraphQL and WebSocket-driven UIs, he combines pragmatic engineering with a security-and-performance mindset. On top of solid academic credentials (MSc in Computer Science), he’s the sort of developer who can exit Vim—efficient, opinionated, and quietly productive.
