ChinaWhat I'm looking for
Full-stack engineer with 6+ years building and shipping web and mobile products end-to-end in TypeScript across React, React Native, and NestJS. I own architecture from database to UI — leading teams on some engagements and running others solo — and increasingly ship LLM/RAG-backed features (Vertex AI, vector search) in production. After years across varied stacks and domains, I'm now looking to bring my expertise into one team long-term, to grow, invest deeply in a product, and build lasting relationships.
