My research focuses on robotics, large language models, and 3D reconstruction.
I build reproducible research tools, explore native software protection, and contribute focused upstream fixes.

¹ Positions are the explicit ranks displayed by GitHub's official Contributors graph, read on 10 November 2026. Current comparisons with the previous snapshot use the same graph settings. Earlier REST observations remain in the full record and are not directly comparable. — means Afloat16 was absent from the complete displayed top 100; it is not an exact rank or a claim of zero contribution. GitHub may cache graph calculations. Graph counts, default-branch author commits and merged PRs are separate metrics. Full record, methodology and data.
Robotics Toolbox also incorporated the circular particle-heading work from #735 into #883, and the trajectory work from #736 into #805, retaining co-authorship. These adoptions are recorded separately from the 395 merged author PRs. Details.
Craft Anything incorporated work from 101 of my original PRs in 11 maintainer integrations. The latest, #1217, combined seven changes to format readers and project launchers, retaining my co-authorship. An earlier squash, #995, omitted my trailer; the maintainer restored attribution separately in #1012. All 11 integrations and their sources.
Claude-Mem adopted the invalid-input regression cases from #5339 into #5336, retaining my co-authorship. My adopted contribution covers the rejection tests; the production numeric-string conversion was implemented by the other PR's author. This adoption is separate from my 108 directly merged PRs.

I isolate the symptom, understand the boundary, write a regression, and make the result inspectable. The six domain utilities have 67 local tests and 36 passing OS/Python CI combinations at the recorded release. These are experimental diagnostics and conversion tools; each repository documents its limits.
