Summary
👤
Senior🎓
Top SchoolKamil Muszyński is a Lead Data Engineer based in Warsaw with over a decade of hands-on experience building backend platforms and data pipelines for maritime and fintech products. He combines deep C++ performance optimization roots with modern data engineering practices, having moved batch cron jobs to Airflow and Argo to scale processing for fleets of hundreds of ships. As a people-oriented technical lead he has run teams of up to 10 engineers, driving refactors that cut KPI computation from hours to minutes and shrinking database footprints by ~75%. He also architected API migrations, introduced GraphQL (Hasura) to speed frontend delivery, and improved release cadence from weekly to multiple daily deployments. Comfortable writing a substantial share of code while handling hiring and stakeholder reporting, he bridges low-level optimization and platform-level reliability. His background in embedded and mobile performance work gives him a practical edge when squeezing latency and resource use out of production systems.
