I work at the quieter end of medicine — teaching machines to read scans, and to be honest about the parts they get wrong. No campus, no tenure clock, no committee to satisfy: just a home laboratory I run myself, where the work answers to no one but the evidence.

Segmentation, classification, detection, and the unglamorous discipline underneath all of them — making models reproducible, explainable, and willing to admit their own uncertainty. That is the part I actually care about.

When I'm not at the bench, I build small software the way I furnish a room: nothing loud, everything intentional. The things I publish aren't badges of identity. They're just tools I wanted to be better, so I made them that way.

A terminal-native downloader built on yt-dlp and rendered with Bubble Tea and Lip Gloss. Concurrent downloads, per-task progress locked to a fixed width so the numbers never judder, a bilingual interface, native notifications, and a failure log that actually respects your time. Go · MIT

A single-file Ghostty config for macOS: JetBrainsMono Nerd Font with a PingFang SC fallback for clean CJK rendering, a theme that follows the system, a translucent window, and iTerm2-flavored keybindings. The terminal is where I live; I'd rather not live somewhere shabby. Maintained with CI that validates the config on every change. Ghostty · MIT

I build things in the open and I send fixes back upstream when the tools I use let me down. My contribution history is the honest record of that; the work that currently matters most is on hister, a private search engine. When a semantic search comes back empty, the one control that can recover results is the similarity slider — so PR #712 brings it into the empty-results state. The re-search is debounced so lowering the threshold mid-drag doesn't tear the control away before you're done, and the empty state shows only the threshold slider (the weight slider, which only re-ranks existing results, stays in the Actions menu where it means something).

If a tool is worth using, it's worth leaving a little better than I found it.

Things I recently took from idea to merge — branch, review, CI, homing in on the details, then a clean squash. Every step green before it moved on.

• ghostty-config #2 — feat: default working directory for new windows. +validate-config clean on both macOS runners, then merged.
• ghostty-config #3 — docs: synced README & CHANGELOG to match; markdownlint, zero warnings.
• ghostty-config v0.2.0 — cut a release whose notes came out of the CHANGELOG, no drift.
• Workflow discipline: branch → PR → CI green → squash → prune, every time. Config + docs ship in one atomic PR.

Reviews offered upstream — code handed back with the polish applied, not just a verdict:

• averygan/reclip #58 — approved a yt-dlp argument-injection (RCE) fix after reproducing the -- separator defense locally against yt-dlp 2026.08.19; suggested hardening is_safe_url against RFC-1918/loopback hosts.
• averygan/reclip #47 — reviewed the m4a-preference audio selector; flagged a consistency gap in the generic merge branch and overlap with #29.

• Write the smallest thing that solves the problem, then delete what remains.
• Badges are welcome; declarations of "impact" belong in journals.
• If a tool needs a tutorial, it isn't finished.
