What I'm looking for

I’m looking for a senior Go backend role where I can own distributed systems end-to-end—high availability, correctness, and security—while building practical AI/LLM agent features with strong engineering collaboration and room to iterate fast.

I’m a senior Go backend engineer with 12 years of industry experience across blockchain, fintech, IM systems, embodied intelligence, AI/LLM applications, and big data. I build high-availability microservices with a strong focus on correctness, security, and long-term stability.

My core strength is distributed backend engineering: microservice architecture (Gin/Kratos/gRPC), data & caching (PostgreSQL/MySQL/Redis), and reusable infrastructure like distributed locks, APM monitoring, and distributed transactions (TCC/Saga). In fintech, I delivered zero-incidents for 2+ years; in IM, I maintained long-term zero downtime.

I also lead end-to-end delivery and modern AI integration—selecting Go AI frameworks (Eino/Blades), implementing multi-Agent workflows with tool calling and SSE streaming, and shipping production deployments. I collaborate smoothly across teams and time zones, and I’ve contributed production-grade open-source libraries (e.g., gobtcsign) to reduce engineering friction.
