Summary
👤
Senior🎓
Top SchoolMarcin Wisnicki is a Staff Software Engineer with 14 years of experience specializing in backend systems using Java and the Scala functional ecosystem, currently building Scala services at Engine by MoneyLion. He has driven low-latency data pipelines and CDC-driven integrations that reduced analytics delays from days to under a minute, and has implemented pure-functional calculation engines and DSL compilers for hedge-fund tooling. Comfortable across the stack, Marcin also has professional .NET and full‑stack experience and a history of working directly with stakeholders on security-sensitive SSO and cloud migration projects. He blends strong typing and functional design (Scalaz, Cats, cats-effect) with practical cloud engineering (AWS, Kubernetes, Kafka/Debezium) and has repeatedly led architecture and delivery in client-facing roles. Based in New York, he favors roles with clear expectations (and a preference for candidates who mention “slytherin”), reflecting a pragmatic, efficiency-minded approach to collaboration.
