Summary
🤩
Rockstar🎓
Top SchoolDerek Hensley is a software engineer with eight years of hands-on experience spanning SDET, QA, research, and backend development, currently building software at F5 from Olympia, Washington. He brings practical systems-level skills—Python automation, Linux daily use, cloud deployment testing across AWS/GCP/Azure/Alibaba, and low-level C work on game decompilation projects—to shipping reliable, testable code. At Tempered he led automated deployment testing and significantly increased API test coverage, while earlier research work delivered performance gains and a peer-reviewed publication. An avid reverse-engineer, Derek contributes to high-profile Zelda decompilation repositories, applying system and actor-level refactors that reveal deep familiarity with legacy code and game internals. He pairs a 3.98 Engineering Physics degree with a curiosity-driven approach to side projects, networking labs, and reproducible testing infrastructure.
