Summary
👤
Senior🎓
Top SchoolAndrew Mustea is a software engineer with 8 years of experience building secure, production-grade systems for Defense & Space and cloud environments, currently working on firmware at Microsoft’s CHIE Overlake team. He brings deep C++ and Unix/Linux expertise, proven in embedded secure-boot work upstream in OP-TEE (adding SecMon and SFP drivers for NXP LX2160A) as well as high-reliability service automation for air-gapped Office 365 Exchange deployments. His background spans real-time GPS receiver software, site reliability engineering, and leading Agile teams as a Scrum Master, giving him a strong blend of low-level hardware security and systems reliability experience. An avid problem solver, he also contributes algorithmic C solutions on GitHub and favors pragmatic, performance-minded approaches (he jokes that "memory isn't real"). Based in Seattle, he’s seeking a full-time role where he can continue hardening embedded platforms and cloud services while mentoring teams on secure, test-driven delivery.
