Poytr1/README.md

Hi there 👋 I'm Pengcheng Xu (PC)

Technical Lead @microsoft working on compilers, runtimes, streaming & LLM-agent systems. I build cloud-scale infrastructure end-to-end — from IR/codegen pipelines to sandboxed multi-tenant runtimes.

  • 🔭 I'm currently working at @microsoft on Microsoft Fabric Eventstreams — owning the core streaming engine, backend compilation pipeline, and IR/CodeGen subsystems.
  • 🌱 I'm currently learning AI Infrastructure — model serving, inference optimization, and the systems that power large-scale LLM workloads.
  • 🤖 I build LLM-agent tooling — AgentJIT (JIT compiler daemon for agents), Changelogue (agent-driven release intelligence), and contribute to sentioxyz.
  • 👯 I want to build agentic applications and am looking to collaborate on AI infra, agent frameworks, and engineering-efficiency / dev tooling.
  • 💬 Ask me about streaming compilers, language servers (LSP), code generation, runtime sandboxing, and agentic workflows.
  • 📫 How to reach me: pooytr1@gmail.com
  • ⚡ Fun fact: LLM agents are fantastic, but I also love stochastic, deterministic systems.

🛠️ Tech I work with: C# · Rust · Go · Python · TypeScript · Java · C++ · SQL

🧠 Focus areas: Compiler construction · IR/CodeGen · LSP · Stream processing · Distributed systems · LLM agents · AI infra
