Summary
👤
SeniorSamuel Lai is a Senior Software and DevOps engineer with 17 years of experience and a decade focused on building scalable backend systems, infrastructure and batch data pipelines using Python, Go and AWS. He has led large-scale data efforts at Lyft and Citymapper—turning brittle scripts into recoverable, production-grade pipelines that processed hundreds of terabytes and thousands of compute nodes—and currently drives reliability and developer productivity at Monzo. Comfortable across services, data stores and frontend tooling, he designs strongly-typed metadata and versioned data stores to preserve lineage and enable experimentation alongside production use. An active open-source contributor, he’s improved FlyteKit’s CLI and added testing and relaunch support, reflecting a pragmatic attention to developer experience. Based in England, he combines deep operational instincts with a transit-hacker’s curiosity, often building internal tools that let non-engineers resolve the majority of data issues.
