Senior🎓
Top SchoolHubert Czerpak is a seasoned software engineer with 11 years of hands-on experience building high-throughput, transactional systems in finance, advertising, and e-commerce, and more recently working at the intersection of cryptocurrencies and renewable energy. He brings deep Java and Scala expertise with a functional-programming bent, having tackled low-latency, concurrent architectures, complex migrations to SAP, and core banking transfer systems. Comfortable across full stacks—from backend services, CI/CD and Dockerized pipelines to responsive front-ends—he has repeatedly improved reliability and developer workflows in large, distributed teams. Currently on a caregiving break in Katowice, he combines enterprise-grade discipline with entrepreneurial grit from running his own startup, and a long history of adapting to evolving tech stacks like Flex, Cassandra, Elasticsearch and Bitcoin-related projects.
