I build AI systems that actually work — agents, orchestration pipelines, and the infra glue that keeps them running.
I spend a lot of time reading source code of projects that millions of people rely on, finding the bugs that nobody noticed, and shipping fixes. Not tutorials. Not wrappers. Core infra.
48 pipeline records audited across flagship Python/AI repositories. The snapshot contains 42 upstream PR records: six are merged and eight remain open with current review or CI state tracked below. The remaining records are closed, duplicate, assignment-gated, or prepared branches awaiting permission. The focus is small, tested fixes in inference, serving, tooling, and data systems.
- nn_inference — C++17 ONNX CPU runtime with SIMD GEMM dispatch and activation memory planning.
- OmniChat Showcase — sanitized case study for a CPU-first multimodal RAG assistant; the operational runtime remains private.
- Portfolio site — live project and upstream-contribution index, refreshed from public GitHub metadata.
