Summary
🤩
Rockstar🎓
Top SchoolCruz Monrreal is a Senior Electrical Engineer in Austin with 14 years of experience building embedded and IoT systems, tooling, and CI/CD infrastructure. He has driven major build-time and automation improvements at Arm and Pelion—cutting Yocto build times from hours to minutes and Dockerizing complex local build environments for repeatability. Cruz pairs low-level firmware and hardware bring-up (radiation-hardened MCUs, space-grade ADCs, SBC test rigs) with developer-facing tooling, having improved Mbed OS, its CLI, and Python tooling for broad cross-platform compatibility. He’s delivered physical datacenter migrations and preserved access for critical services while documenting architectures for team handoffs. An open-source contributor to prominent Arm Mbed projects, he blends pragmatic debug-driven fixes with prototype hardware like USB3 Mux devices to accelerate testing. Known for turning fiddly integration problems into repeatable systems, he thrives at the intersection of hardware, firmware, and developer productivity.
