Summary
👤
Senior🎓
Top SchoolMarcin Kasprowicz is a Senior Software Engineer based in Krakow with 10 years of experience designing and delivering high-throughput, event-driven systems across backend and frontend stacks. He has led cross-functional teams to build mission-critical platforms—from a parcel-sorting event system handling 100k packages/day using Elixir/CQRS to payment infrastructure processing billions NOK—and reduced operational costs through pragmatic AWS and Terraform migrations. Comfortable across JVM, Node.js/TypeScript, and frontend frameworks, he pairs hands-on coding with architecture and rollout leadership, including zero-downtime migrations of customer-facing apps. Curious by nature, he explores functional approaches (Elixir proofs-of-concept) alongside production-grade engineering, and maintains a public technical presence via his Medium writing.
