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. 38 merged PRs across 2 repos:

gastownhall/gascity

• #5138 — fix(session): thread liveness-probe observation into heal-state instead of hardcoding Observed:true
• #4485 — fix(supervisor): back off structural init failures far longer than transient ones
• #4875 — fix(dolt): send SIGTERM before SIGKILL in run_bounded's python3 fallback
• #4384 — fix(cmd/gc): validate explicit city path before scanning registry rig bindings
• #4405 — fix(runtime/k8s): propagate Nudge/SendKeys transport errors
• …and 32 more — see all 37

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.
