Summary
👤
Senior🎓
Top SchoolChad Zawistowski is a Staff Software Engineer based in Boulder with 11 years of hands-on experience building low-level systems, drivers, and firmware, currently advancing compute at Groq. He has a strong track record at Microsoft where he cut OS boot times by 50%, architected Azure IoT EFLOW servicing, and optimized Windows ML Container to enable ML on edge devices with dramatically reduced footprint. A pragmatic advocate for open source, Chad has bootstrapped internal Linux distributions, taught Git migration strategies, and helped port critical components like the Unified Write Filter to IoT Core. He combines systems-level curiosity with practical tooling—writing build and verification tools that halved build breaks and creating transpilers that slashed engineering time. Comfortable across firmware, OS internals, and packaging, he brings a habit of reducing surface area and dependencies to deliver efficient, auditable solutions. His minor in philosophy hints at a thoughtful, systems-oriented approach to problem solving beyond pure code.
