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. 48 merged PRs across 2 repos:

gastownhall/gascity

• #4927 — fix(wisp-gc): reap rootless plain-task wisps
• #4946 — fix(doctor): order-firing-current timeout is advisory, not blocking
• #4925 — fix(import): local-in-git pack imports lock to HEAD, not latest tag
• #4898 — fix(gc): stop bd's dolt-unreachable message from suggesting a conflicting bd dolt start
• #5302 — fix(dashboard): add Claude 5-gen models to TRUE_CONTEXT_WINDOWS
• …and 42 more — see all 47

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.
