What I'm looking for

I’m looking for a team where I can own Go backend architecture and reliability end-to-end—high-availability microservices, blockchain/fintech-grade correctness, and AI/LLM Agent features—while collaborating smoothly and improving reusable engineering foundations.

I’m a senior Go backend engineer with 12 years of experience across blockchain, fintech, IM systems, and AI/LLM applications. I build microservice architectures with Gin/Kratos/gRPC, PostgreSQL/MySQL/Redis, and message middleware like RocketMQ/RabbitMQ/Kafka—backed by strong system reliability work such as “financial system 2+ years zero incidents” and IM performance at “2,100+ member groups” with “message latency <300ms” and long-term stability with “zero incidents.”

I also enjoy pushing engineering depth: reusable distributed locks, APM monitoring, and distributed transactions (TCC, Saga), plus Go compiler-level work (generics, AST metaprogramming, and 6 custom protoc plugins). Recently I designed and delivered an AI Intelligent Assistant multi-Agent platform (Agent loop + Tool Calling + SSE streaming) and contribute open-source production-grade components like “gobtcsign” for Bitcoin transaction signing: https://github.com/yylego/gobtcsign.
