What I'm looking for

I'm looking to build production AI infrastructure and cloud-native products, applying Go, Python, React, AWS, and MLOps experience across global and APAC teams.

At Lo Kee, I architected Go and Python microservices supporting 10,000+ concurrent users, reduced server costs by 30% through AWS EC2 auto-scaling and Docker, and shipped an AI Chat with Data feature using LangChain, FastAPI, AWS ECS, and Pinecone.

Previously at ASTRI and Shopline HK, I modernized monoliths into AWS microservices, built React and TypeScript portals, optimized Go, PostgreSQL, and Redis services, and mentored junior developers. I bridge US, EU, and APAC technical ecosystems through English and Mandarin technical documentation and cross-border data compliance work.
