Subject Matter Expert
Zurich, Zurich, Switzerland
Summary
👤
SeniorMerlin Unterfinger is a Software Engineer and Data Scientist with eight years' experience, currently serving as a Subject Matter Expert at Swiss Federal Railways (SBB) focused on mobility simulation and geographic information science. He combines rigorous spatial analysis with production-ready infrastructure skills—designing spatial databases, managing ETL and job schedulers, connecting APIs, and deploying tools in containers and pods. Merlin builds interactive dashboards to translate complex geospatial models into actionable insights for transport planning and operations. His open-source work (github.com/munterfi) demonstrates a hands-on approach to reproducible, shareable tooling that complements his enterprise projects. Colleagues rely on him to bridge research-grade simulation methods with scalable, maintainable delivery pipelines. Less obvious: he routinely blends GIS theory with pragmatic software engineering to reduce model-to-production friction in large, real-world mobility systems.
