Swift + Clang + LLVM
Compiler work that shipped
Delivered Swift/C++ interoperability work in public Swift toolchains and handled architecture-sensitive compiler integration paths.
Compiler Engineer • AI Systems • Performance
Compiler and AI systems engineering.Built for production reliability.
I design and ship compiler/toolchain features, low-level performance optimizations, and production AI infrastructure. My work spans Swift/C++ interoperability, LLVM/Clang vectorization, and model bring-up on accelerator hardware.

Why Me
The best of me is execution under real pressure
RISC-V RVV + CI
Performance engineering with guardrails
Improved RISC-V vector workloads through RVV heuristics while adding benchmark + regression coverage to keep wins durable.
TTNN + Multi-cloud
AI systems that survive production
Built model bring-ups, inference deployment, and operational reliability workflows across multiple cloud environments.
