Summary
🤩
Rockstar🎓
Top SchoolGlenn Andrews is an embedded software engineer and instructor with eight years of focused experience and a long career in bare-metal C and assembly across avionics, automotive, defence and consumer electronics. He teaches UW’s Certificate in Embedded and Real-Time Systems Programming while contributing to cutting-edge VR research at Meta, bridging practical firmware skills with academic instruction. Glenn is an active open-source contributor to the Zephyr RTOS—working on the State Machine Framework and device drivers—which highlights his expertise in real-time systems and hardware interfaces. His background includes long-term systems and avionics firmware roles, and a subtle strength is translating safety-critical, resource-constrained designs into maintainable code and documentation. Based in Tacoma, he combines hands-on driver development with a knack for turning low-level complexity into teachable, production-ready solutions.
