AI/LLM & systems software engineer — agentic systems, RAG, full-stack. San Francisco Bay Area.

I build LLM-powered products end to end — FastAPI + LangChain backends, React frontends — and contribute fixes upstream to open-source multi-agent orchestration systems.

Fixes merged across the gastownhall ecosystem — an open-source multi-agent orchestration platform — each reviewed and approved by independent maintainers. 81 merged PRs across 3 repos:

gastownhall/gascity

• #5614 — fix(events): truncate a NUL-padded tail left by an unclean shutdown
• #4547 — fix(cmd/gc): order dispatch searches all configured formula layers, not just the order's own
• #5617 — fix(tmux): don't clear-before-paste on an attached session
• #5613 — fix(reaper): expired-nudge cleanup now closes rig-scoped shadows too
• #4926 — fix(searchpath): find Nix-installed provider CLIs
• …and 70 more — see all 75

gastownhall/gastown

• #4173 — fix(memories): tolerate non-string values in bd kv list

gastownhall/gascity-packs

• #320 — fix(gastown/witness): re-verify liveness before delete, content-check merges past rebase/squash
• #322 — fix(gastown/witness): complete crashed submit-and-exit handoff instead of resetting to pool
• #325 — fix(gastown/witness): add --include-infra to bd list molecule queries
• #314 — docs(gastown/refinery): note mr/pr mode is GitHub-specific
• #321 — feat(superpowers): vendor missing systematic-debugging skill

Themes: concurrency races, operational guardrails, and failure-mode UX in long-running agent systems.

Maintainer on #3469: "a careful, surgical fix — I especially appreciate that you keyed the dedup signature on the set of active conditions."

I also file actionable bug reports that maintainers act on — e.g. #2814 (bundled Dolt 2.0.8 corruption → version pin) and #2846 (compactor quarantine race starving GC) — both closed with a by-name thanks from a core committer.
