Senior🎓
Top SchoolEthan Reesor is a seasoned engineering leader and CTO based in Austin with 14 years of experience building systems across embedded, database, and developer tooling domains. He combines hands-on backend and full‑stack engineering with product leadership, having progressed from embedded systems and space‑grade software to principal engineering and now executive tech leadership at AthletiFi. Ethan is an active open-source contributor to notable Go projects—helping evolve the Yaegi Go interpreter, enhance the VS Code Go extension, and implement core database driver primitives in go-mysql-server—demonstrating deep expertise in compilers, tooling, and database internals. His embedded work on TinyGo shows low-level proficiency with ARM Cortex‑M fault handling and power management, a less obvious strength for a CTO. Comfortable spanning hardware to cloud, he excels at turning complex technical requirements into reliable, reusable infrastructure and developer experiences.
