Summary
🤩
Rockstar🎓
Top SchoolYuhui Zheng is a firmware-focused software development engineer with nine years of experience building platform firmware, tooling, and IoT connectivity at AWS and earlier embedded roles at EchoStar. Currently working on BIOS and platform firmware at AWS in Seattle, he brings deep embedded systems expertise—ranging from FreeRTOS kernel work and POSIX-compliance fixes in Amazon FreeRTOS to antenna and set-top-box firmware. He combines an engineering mindset for real-world problem solving with strong automation and tooling skills developed across big-data test/performance and device services teams. Yuhui holds an MS in Computer Engineering from Purdue and a BE in Electrical and Electronics Engineering, a background that underpins his low-level systems and multithreading work (including atomic operation improvements). Colleagues rely on him for pragmatic, correctness-first fixes that improve robustness in production-constrained devices.
