- Compiler Engineer @ Microsoft
- Working on the compiler for MAIA
- Drove compiler improvements that delivered 100x performance gains on gpt-oss matmuls
- Landed a large set of optimizations that yielded ~10x better performance for open-source models on MAIA (llama, gpt-oss)
- Designed and implemented a system for tracking optimization gaps across models and monitoring regressions
- Optimized triton kernels targeting inference for several LLMs
- Made a few LLVM upstream contributions, like this one
- Working on the compiler for MAIA
