Summary
👤
Senior🎓
Top SchoolIan Gregson is a senior software engineer with 11 years of focused experience building blockchain, security, and high-performance backend systems across Europe and the US. He blends polyglot engineering (Node.js/TypeScript, Go, and functional patterns) with hands-on wallet and tooling development for privacy-first blockchains like Midnight, and has worked on both incubated and spun-out teams at IOHK/Shielded Technologies. Ian has a strong track record in production-grade infrastructure—endpoint clients, vulnerability scanning, Kubernetes deployments, and large-scale Bitcoin tooling—and contributed testing and NestJS gRPC support to the widely used ts-proto TypeScript protobuf generator. He’s equally comfortable leading small teams, mentoring engineers, and converting legacy systems into scalable microservices while keeping security and composability front and center. Based in Madrid, he pursues distributed systems study (Cosmos SDK, P2P) and often applies functional-effect frameworks to make complex blockchain workflows type-safe and error-resilient.
