Compilers & Toolchains
Swift/Clang interop, LLVM codegen, Apple Silicon bring-up. Deep compiler internals that ship in production toolchains.
Systems Engineer
I build the infrastructure that makes software possible.
Compiler internals, low-level performance tuning, secure cloud architecture, and production AI product delivery. From Swift/Clang toolchains to RISC-V optimization, multi-tenant LLM systems, and accelerator model bring-ups.

What I Do
Four domains, one systems mindset
AI Infrastructure
Multi-tenant RAG pipelines, Bedrock/Claude orchestration, structured outputs, guardrails, and observability at scale.
Performance Engineering
RISC-V RVV vectorization tuning, cost-model optimization, benchmarking, regression coverage, and CI automation.
Accelerator Bring-ups
TTNN vision model implementations on Tenstorrent hardware — MaskFormer, DPT-Large, YOLOS-small with profiling artifacts.
Why Teams Hire Me
Deep systems depth, plus product execution
Swift + Clang + Apple Silicon
Compiler internals that ship
Built Swift/C++ interoperability across Swift/Clang, supported Apple Silicon compiler migration, and shipped reliability tooling used in daily release workflows.
RISC-V RVV + CI
Performance with hard guardrails
Improved RISC-V RVV workloads with LLVM/Clang cost-model and codegen tuning, backed by benchmarks, regression coverage, and CI automation.
AWS + Bedrock + Terraform
Product-grade AI systems
Designed and shipped multi-tenant AI products end-to-end: ingestion, embeddings, retrieval, orchestration, guardrails, observability, and production deployment.
TTNN + Validation
Accelerator bring-ups
Implemented TTNN vision model bring-ups (MaskFormer, DPT-Large, YOLOS-small) with profiling, validation, and reproducible execution paths.
Proof of Work
Selected execution across compilers, cloud AI, and accelerators
Swift/C++ interoperability
Implemented getter/setter interop and contributed production compiler reliability tooling across the Swift/Clang toolchain.
