Summary
👤
Senior🎓
Top SchoolZbigniew Rzepka is a Senior Software Engineer based in Krakow with 11 years of backend-focused experience, primarily in Python, delivering reliable data and reporting pipelines at scale. He currently builds reporting automation and secure data integrations at Revolut, and has delivered ETL, AWS infrastructure and microservices for gaming and finance teams. Comfortable across languages and stacks, he has hands-on experience debugging low-level issues—most notably locating a production-only memory leak in a compiled C++ game server on AWS EC2. His background spans startups to enterprise banking, combining pragmatic engineering with stakeholder management and a strong focus on data consistency. Zbigniew pairs an academic foundation in computational engineering with a preference for solving thorny production problems rather than following trends.
