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 4 November 2026. This refresh uses the same graph settings for all projects; 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.
TD-MPC2 (996 ★, graph position #6): preserve target-Q history and evaluation mode during model conversion. The implementation from #98 was cherry-picked with Afloat16 authorship; the original PR was closed without merging. Together with the repositories above, this makes 30 upstream projects with accepted contributions.
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 126 merged author PRs. Details.
Craft Anything also adopted work from 60 original author PRs through eight maintainer integrations: #645 · #648 · #649 · #652 · #653 · #656 · #683 · #722. All eight default-branch commits retain my co-authorship; these adoptions are recorded separately from the 126 merged author PRs. Evidence.
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 two directly merged PRs. Evidence.

How I work: 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.
