Longchang Liu

Currently a Backend Engineer Intern at Alibaba (Amap), traversing the stack from Java JVM internals to OS kernels. I am passionate about building deterministic, resilient infrastructures for the next generation of AI Agentic Workflows.

With prior experience at Tencent and iMile, I specialize in solving high-concurrency challenges and optimizing RAG pipelines for enterprise-grade performance.
