Senior full-stack engineer with 6 years of professional experience — I build complete web applications, with particular depth on the backend. My backend core is Java and Spring Boot: I've engineered and maintained production systems for banking clients, with a strong focus on clean data handling, SQL optimization, and reliable, well-tested code. I also build backends in Node.js, and I'm comfortable across MySQL, PostgreSQL, MongoDB, and REST API design. On the frontend, I build production interfaces with React, Next.js, and TypeScript. Because I work across the full stack, I can take a feature from database to API to UI — or step into an existing codebase on either side and find my way around. I've also built AI agent systems: AgentRoute Studio, an open-source goal-driven agent platform with verification layers, multi-model routing, risk gates, and budget monitoring. If you're integrating an LLM and want it reliable rather than just a demo, I can help there too. I'm based in China and work comfortably with both English and Japanese-speaking clients in writing — I spent years collaborating with Japanese teams. What I bring to every project: a senior engineer's discipline around reliability, clear communication, and code I'd be willing to maintain myself. Tell me what you're building and I'll tell you honestly how I'd approach it — and whether I'm the right fit.
