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. 63 merged PRs across 2 repos:

gastownhall/gascity

• #5301 — fix(events): normalize caller-supplied Ts to the recorder's zone
• #5270 — fix(doctor): order-firing-current reads live suspension state, not just the deprecated rig.Suspended field
• #5261 — docs(session): clarify primed_at as delivery-attempted, not consumed
• #5258 — fix(dispatch): default gc.kind on plain attempt-recipe children
• #5253 — fix(dolt-cleanup): drop rss= from the reap-stage ps scan
• …and 57 more — see all 62

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.
