AI/ML engineer at Zasti Inc. (Ashburn, VA). M.S. in Computer Science, University of Cincinnati.
I work on the performance and numerical correctness of scientific and ML software. Most of my open-source work is algorithmic speedups and correctness fixes in libraries that other people build on.

| Project | Contribution | Result |
|---|---|---|
| Google JAX | Batched lexsort / unique(axis=...): new batch_size keyword, designed with a core maintainer over six review rounds |
Compile time no longer grows with the number of keys: jnp.unique 15.5 s → 0.28 s; lexsort on 100 keys 162 s → 0.22 s |
| statsmodels | Closed-form leave-one-out influence measures (dfbetas, dffits, cov_ratio, studentized residuals); closes maintainer issue #9009 |
35 s → 2.7 ms at n = 10,000; matches R's influence.measures to 12 decimals |
| xarray | interp skips sortby on already-sorted coordinates |
Vectorized interp 164 ms → 2.9 ms |
| Hugging Face candle | Row tiling in the CPU quantized matmul for prefill | About 1.45x faster prefill for Q4K / Q8_0; outputs bit-identical |
| Bokeh | Row/Column layout reserves room for aligned borders (BokehJS) | Fixes cropped axes and legends; milestone 4.0, backported |
| Apple MLX (mlx-lm) | Left-padding mask in batched generation | Fixes wrong logits for left-padded batches in two model families |
| Google JAX | zeta JVP rule, pareto support boundary |
Correct values and gradients outside the domain and at the support edge |
| LangSmith SDK | Keep the HTTP response on raise_for_status_with_text errors |
Shipped in v0.14.2 |
| CISA CSET (US DHS) | Raise the PBKDF2 work factor to OWASP guidance | Password-hash hardening in CISA's Cyber Security Evaluation Tool |
| USGS dataretrieval (US DOI) | Open-ended (..) date ranges in the OGC client |
Fixes silently unfiltered results and HTTP 400s in the official USGS water-data client |
| Sandia National Laboratories pyGSTi | Default POVM for circuits on a subset of a model's qubits; fixes #721, a 0.11 release blocker | Circuits on part of a multi-qubit model no longer fail with "Missing POVM"; merged by a Sandia maintainer |
| Microsoft Olive | Declare requests as an install dependency |
Fixes import olive failing after a fresh install; also hit by Microsoft's olive-recipes |
| ONNX (Linux Foundation AI) | Define DynamicQuantizeLinear scale for all-zero inputs |
Spec and reference fix: all-zero inputs no longer give a zero scale (NaN downstream); now matches ONNX Runtime |
| Apache ShenYu (Apache Software Foundation) | Render non-JSON API debug responses as plain text; fixes security issue #614 | The admin console no longer renders upstream response bodies as HTML; merged by a ShenYu PMC member |
| pylint | Fix pyreverse hang/RecursionError with --all-associated; closes #3602 |
Class diagrams of code that rebuilds classes on each inference no longer hang or crash; merged by the pylint maintainer and backported to 4.1.x |
Rust cc crate (rust-lang/cc-rs) |
Stop forwarding -Cprofile-generate/-Cprofile-use to the C compiler; fixes #1986 |
PGO builds no longer segfault when the C compiler's LLVM differs from rustc's (the cause behind rust-lang/rust#163640); merged by the cc-rs maintainer the same day |
| ogx | Dependency floor for the inline provider | Fixes a user-reported install failure |
| cartography (CNCF) | Handle empty Google Workspace groups | Fixes a sync crash |
