👋 Hey, I'm Shawn.

I'm the dude who took apart toasters as a kid to find out why AND how they worked.

Fifteen years in tech turned that into React, TypeScript, AI pipelines, and an unhealthy number of repos. Then the industry buried the fun part under DSA interviews and "quality with velocity" metrics... so I went on a quest to get the wonder back.

Now I build things that light up when I tell them to. And it feels like the first time I put a hover state on a button with jQuery.

• open-brain - Semantic memory layer for AI agents. Postgres + pgvector + MCP. Capture a thought, it gets embedded, classified, and filed. Ask a question in natural language, it understands what you meant. 7 tools, one brain. TypeScript + Python.

• mediascribe - Extract structured insights from audio and video recordings. On PyPI and Homebrew. Python.

• WindWatts - Open-source wind energy assessment tool for the National Lab of the Rockies. Mobile UI, public API docs, shareable deep-link architecture. React, TypeScript, FastAPI. 25 PRs merged.

• claude-code-clone - Built a minimal clone of Claude Code from scratch. 42 features, zero human-written code, three agent sessions. The agentic loop is just send, detect, execute, feed back, repeat. That's it.

• salazar - AI agent framework. The one I model all my agentic workflows around. Inspired by Anthropic research on long running autonomous agent harnesses.

Vibe coding with guardrails. Spec-driven development where the AI handles implementation and the human architects the output. Agentic workflows, MCP servers, CLI tools designed for LLM consumption... and putting the art back into a profession that forgot it was one.

Writing a field guide about it. Working title: Kindling.

Staff engineer turned independent. I build AI tools and automation for small businesses: the operations layer they can't afford to hire for. petrosindustries.com
