Senior🎓
Top SchoolNicolas Henin is a senior Haskell software engineer and Innovation Technical Architect with a decade of experience building high-assurance blockchain and distributed systems, currently at Input Output (IOHK) in Cyprus. He has progressed from Haskell/Plutus consultancy and Marlowe engineering to leading innovation architecture, blending deep functional-programming expertise with practical product delivery. Nicolas founded and maintains the Marlowe Foundation effort to transition Marlowe to a community-driven project, and has shipped both Haskell core runtimes and a TypeScript SDK for the stack. His background spans consensus protocol design, high-throughput systems, and CQRS/event-sourced architectures developed across startups and scaled teams. Known for mentoring juniors and open collaboration, he pairs rigorous academic foundations in maths/computing with hands-on system optimization and formal reasoning. Outside core blockchain work, he brings unusual cross-domain experience—from biometric platforms to conversational AI—that informs pragmatic, resilient architecture decisions.
