Summary
🤩
Rockstar🎓
Top SchoolGeorge Beckstein is a pragmatic technology leader and CTO with a decade of experience designing medical wearables, IoT systems, and signal‑processing‑heavy embedded firmware. He has led product and engineering teams from prototype to regulated, continuous ear‑worn SpO2 monitoring at OxiWear and has deep hands‑on experience across embedded Linux, RTOS, device drivers, and sensor integration. An active contributor to Arm Mbed OS and the mcuboot secure bootloader, he brings proven low‑level expertise in boot processes, flash management, and hardware integration for constrained devices. His background spans startups and industry—SparkFun tutorials to Intel wearable co‑ops—so he balances clear documentation and teaching with production-grade engineering. Based in Buffalo, NY, he pairs systems thinking with practical toolbuilding (and an uncanny fondness for cereal), making him adept at turning complex signal and hardware challenges into shipped products.
