I enjoy turning complex systems into reliable, understandable products.
I build backend systems for asynchronous workloads, real-time communication, voice AI workflows, and data-intensive products. Most recently, I worked on production infrastructure for generative AI workflows at Alibaba International and built VivaTrace, a voice-first AI oral-defense platform.
