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. 21 merged PRs across 2 repos:

gastownhall/gascity

• #4406 — fix(cmd/gc): gc init --skip-provider-readiness accepts any builtin provider
• #4442 — fix(cmd/gc): gc hook --claim never adopts mail message beads as work
• #4248 — fix(doctor): warn when beads-store silently fell back to BdStore
• #4219 — fix(runproj): warming snapshot no longer marshals historicalLanes/recentChanges as null
• #4216 — fix(cmd/gc): lint no longer flags the documented pool-disable form as a named-session conflict
• …and 15 more — see all 20

gastownhall/gastown

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

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.
