I am an open-source contributor focused on reliable developer tools, terminal workflows, and performance-sensitive systems.
- I turn reproducible problems into focused patches, regression tests, and measurable results.
- I contribute to deepcoldy/botmux, improving terminal input, Lark interactions, and feedback reliability.
- I care about deterministic tests, narrow interfaces, safe fallbacks, and performance evidence.

| Status | Contribution | Engineering result |
|---|---|---|
| Merged | botmux #1419 — fail closed without requester identity | Prevented requester-only feedback on cards with no stored requester identity; added a regression test that checks no feedback revision is written. All CI checks passed. |
| Merged | botmux #1312 — add paste protocol support to bare PTY input | Added bracketed-paste handling for long or multiline OpenCode V2 messages on raw PTY while preserving typing behavior for slash commands and short single-line input. |
| Merged | botmux #1314 — optimize TraeX session-recovery lookup | Replaced full-tree recursion with a SQLite-indexed fast path, depth-bounded date traversal, and bounded miss backoff. In a deterministic 200-sidecar fallback fixture, stat calls fell from 204 to 0 with at most 4 directory reads. |
| Merged | botmux #1293 — eliminate a history-ownership test timing race | Replaced fixed-delay test orchestration with an Enter-event happens-before boundary, preserving ownership filtering and retry coverage. |
| Open · awaiting review | botmux #1418 — reject stale feedback card callbacks | Added card version checks inside the SQLite write transaction so delayed callbacks cannot restore an older feedback choice or repaint the card. |
| Open · awaiting review | botmux #1417 — serialize live card toggle updates | Routed live-card toggle updates through the existing patch queue to prevent an older in-flight update from restoring stale display state. |
