Saul Reynolds-haertle
Software Engineer at Stealth Startup
Oakland, California, United States
Summary
👤
Senior🎓
Top SchoolSaul Reynolds-haertle is a versatile software engineer with 16 years of experience building systems that span robotics research to production web backends, currently engineering at a stealth startup in Oakland. He combines academic robotics pedigree—contributions to humanoid platforms and the DART simulator—with industry experience at Google, Saildrone, and growth-stage startups delivering scalable backend services and analytics. Comfortable across languages and layers, Saul has shipped collision-profiling tools for simulation and meaningful UX and maintainability improvements in popular open-source projects like Tridactyl. His work favors practical, testable solutions that bridge research-grade algorithms and customer-facing systems, and he’s equally likely to prototype FPGA-level or UI work when the problem demands it.
