Hi, I'm Jie Fu (傅杰) 👋

Compiler & Runtime Engineer | OpenJDK Reviewer & Committer.
Currently focused on AI compilation — MLIR, Triton, and code generation for accelerators.

Ph.D. in Computer Architecture, Institute of Computing Technology, CAS.
I got into compilers by building a JVM for a homegrown processor that didn't have one yet.

💡 Focus Areas

• AI Compilers — MLIR passes & pattern rewrites, Triton compiler internals, accelerator backend enablement
• Runtimes & Systems — HotSpot JIT internals, GC, memory models
• Compiler Backends & Optimization — code generation, vectorization, and profile-guided optimization

---

🏆 Open Source

• OpenJDK Reviewer & Committer (Compiler Area) — A decade on HotSpot C2/Runtime, and one of the top contributors to the main openjdk/jdk repository
• Triton — correctness fixes in the compile pipeline
• vLLM · llama.cpp — model support, performance fixes, CPU inference enablement
• LLVM — commit access (compiler compatibility, code quality, and build stability)
