Senior

Roy Lee is a pragmatic full-stack software engineer with 9 years of experience building performant web and embedded systems, currently based in San Jose and working at Walmart Global Tech. He combines strong frontend expertise with low-level hardware integration—contributing drivers and platform plugins for SONiC and Open Network Linux that handle SFP transceivers, thermal sensors, PSUs, and fan control. Roy has shipped responsive, production-grade SaaS and e-commerce features, optimized backend throughput with Redis and NGINX, and has a history of improving product metrics through both engineering and product roles. Comfortable across the stack, he pairs a Hack Reactor engineering background with an economics degree from Penn State, bringing analytical rigor to system design and hardware-software co‑integration. An under-the-radar strength is his proven ability to bridge device-level constraints and cloud-scale services to deliver reliable, measurable improvements.
