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. 93 merged PRs across 3 repos:

gastownhall/gascity

• #5939 — fix(nudge): add a drop verb for stale pending nudges instead of requiring manual state.json surgery
• #5938 — fix(sessionlog): thread the transcript entry's own timestamp through to Fact.At instead of stamping now
• #5933 — fix(mail): respect cfg.Mail.RetentionTTL in the nudge-mail sweep instead of a hardcoded 60m
• #5913 — fix(supervisor): guard the supervisor socket path against Unix domain socket length limits
• #5756 — fix(events): fail a short single-record write instead of counting it as written
• …and 82 more — see all 87

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
• …and 3 more — see all 5

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.
