Rockstar🎓
Top SchoolIan Rees is a Principal software engineer with 14 years of experience applying rigorous, research-driven engineering to transportation and scientific software. Based in Emeryville, he builds tooling to understand and improve transit systems, having led architecture and data pipeline work for Transitland and authored open-source GTFS libraries while integrating multimodal routing with Valhalla. His background as a PhD scientist and postdoc informs a pragmatic approach to complex data problems—he’s done everything from migrating build systems at national labs to designing databases and visualization tools for imaging research. Active in open data, he contributed data engineering and scripting to the widely used transitland-atlas feed directory, focusing on feed integration, validation, and compatibility. Colleagues know him for turning academic rigor into production-quality systems that make messy, real-world data reliably useful.
