Rockstar🎓
Top SchoolDavid Sanders is a Senior Software Engineer with 12 years of experience, currently at Microsoft after senior roles at Postman and HL, and a BS in Computer Science from UC Santa Barbara. He reliably ships clean, efficient systems across the full stack, with a strong track record in backend, frontend, QA, and security engineering. An active open-source contributor, David has improved test infrastructure for TensorFlow.js, hardened WebAuthn certificate handling in py_webauthn, and touched major projects like Electron, Django, and Signal Desktop. He brings deep systems knowledge—from SIP server internals in OpenSIPS to executable-format tooling in LIEF—and a knack for modernizing legacy code (e.g., async/await test refactors and cryptography library migrations). Colleagues value his blend of pragmatic problem-solving and attention to correctness, evidenced by fixes that improve both security and long-term maintainability. Based in Santa Barbara, he pairs broad language and platform fluency with a history of leadership in community-driven projects dating back to game-mod and GSoC work.
