Summary
🤩
Rockstar🎓
Top SchoolPaul Mach is a senior software engineer in Oakland with 15 years of experience building production-grade systems across front-end and back-end stacks. He brings deep applied-math and computational-geometry expertise from a PhD in Applied Mathematics to practical engineering problems, notably contributing UI features to the widely used OpenStreetMap iD editor and maintaining the Go geometry library orb for robust spatial handling and WKB/database interoperability. At Strava he shipped frontend training tools and a custom heatmap aggregation service, and he currently drives analytics-focused engineering at Cisco Tetration. Paul blends a researcher's attention to algorithmic detail with a practitioner’s focus on tests, refactors, and shipping reliable tooling. He also has an uncommon background as a former professional cyclist, which shaped his disciplined, performance-oriented approach to long-term projects.
