Summary
🤩
Rockstar🎓
Top SchoolWilliam Sengir is a pragmatic software engineer with 7 years of experience building secure, maintainable platform and product services at Amazon, currently shaping the Embedded Linux Platform for Project Kuiper. He combines front-end architecture and tooling expertise—demonstrated by leading the Brand Referral Bonus launch and centralizing permissions—with system-level work on runtimes, security mechanisms, and metrics for satellite platforms. A strong believer in readable, explicit code, he also contributes to the Zig compiler’s LLVM backend to improve DWARF debugging and runtime safety, reflecting deep systems and toolchain interests. With a 4.0 CS degree from ASU and personal projects in OS, compiler, and emulator development, he brings both production impact and low-level curiosity to complex engineering challenges.
