Summary
👤
Senior🎓
Top SchoolJan Bernatik is a seasoned software engineering leader with nine years in senior management and a two-decade technical foundation spanning embedded systems to blockchain protocol engineering. Currently Sr. Manager at Flow in Canada, he leads teams building the Cadence smart contract language and a core execution node, and drove the Crescendo release—the largest Flow network upgrade since launch. Previously at Dapper Labs and AWS, he launched SiteWise Edge and led initiatives to scale transaction throughput and enable permissionless smart contract deployment. Jan pairs hands-on backend contributions to prominent open-source projects like onflow/flow-go with a track record of delivering complex, production-grade distributed systems. His background in embedded, video distribution, and industrial IoT gives him an uncommon systems-to-protocol perspective that helps bridge low-level engineering trade-offs and high-level product goals. He holds a master’s in electrical engineering and has repeatedly led cross-disciplinary teams to turn ambitious technical visions into shipped releases.
