Backend & Systems Engineer | AI Systems | FastAPI | PostgreSQL | Agent Infrastructure

I build automation pipelines, agent harnesses, and local-first systems where humans stay in the loop—inspectable context, explicit gates, and production-shaped backends (FastAPI, PostgreSQL, Docker, observability).

Problem → Solution → Impact

  • Problem: Agent workflows lose intent across sessions; untrusted content reaches LLMs; production ops lack inspectable, human-gated context.
  • Solution: Guard–Guide–Build — SCP (input safety), OpenHarness (handoffs + gates), OpenGrimoire (context graph), plus production platform (CaptionPipeline / Platform API).
  • Impact: CaptionPipeline: 256+ caption files, 330+ content hours, <1% errors across 9 production feeds (case study); SCP: 16/16 promptfoo tier probes (OWASP LLM01/LLM06); OpenHarness: harness pin-able by commit SHA, autoresearch Tier B 5/5 on foam-pkm + frontend-a2ui skills (Jun 2026).

Case studies

  • CaptionPipeline — automated WhisperX → SCC captions across 9 feeds; Dec 2025 snapshot: 93.5%+ success, peaks 121 files/day → portfolio kit
  • SCP guardrail — 16/16 promptfoo injection/reversal probes before LLM context → SCP README § Impact
  • Agent harness eval — Tier B 5/5 on foam-pkm and frontend-a2ui skills (2026-06) → OpenHarness + MiscRepos autoresearch harness
