Summary
🤩
Rockstar🎓
Top SchoolBilly Zhu is a compiler engineer with a decade of experience building production-quality tooling for AI and systems software, currently working on heterogeneous compiler and runtime integration at Modular. He previously led compiler development for SambaNova’s reconfigurable dataflow hardware and has deep hands-on experience in MLIR/LLVM, including work on debug-info import, caching, and leak fixes that improved compiler performance and reliability. Billy also has full-stack roots from supporting large-scale autograding infrastructure at Carnegie Mellon’s Autolab, where he shipped backend, API, and UX fixes used by thousands of students. Comfortable across C++, Python, and web stacks, he brings a pragmatic balance of systems-level rigor and product-minded engineering; unusually, his background spans both low-level compiler internals and user-facing education tooling.
