I build things that let AI systems do real work: MCP servers, agent workflows, and production software with an LLM somewhere in the loop that has to be right.
Founder of Civic-Chain, a govtech company working on municipal financial transparency. Most of what is public here came out of that, or out of trying to automate a part of it.
geo-inspector-mcp · TypeScript An MCP server that inspects a website's AI-search readiness. Four tools, every parser a pure function with fixture tests, all HTTP through one capped and redirect-limited helper. Published on npm and listed in the official MCP Registry.
ai-visibility-audit · Claude Code plugin The workflow layer over those tools: a skill that orchestrates them into a scored, client-ready report. The scoring is a bundled zero-dependency script, so the same site state always produces the same number. Claude writes the words and never invents the math. That split is the whole design.
procurement-forecast-bot · TypeScript Finds planned federal procurement before any RFP exists, scores it 0-100, and emails a ranked digest. Four public agency sources, three of them undocumented and reverse-engineered off the agencies' own front ends. An optional LLM pass judges fit against a cached capability profile, with a hard per-run item cap as a cost ceiling. It ships switched off, because a model judging against an unreviewed profile is worse than no model at all.
Owner's Manual · Python + vanilla JS An interactive course for the PSPO I exam: 14 modules, 317 questions, 164 flashcards and 20 branching decision simulations, shipped as one self-contained HTML file with no framework and no dependencies. Open the demo. Content is data rather than markup, which is how seven parallel authoring agents working from one checked-in spec produced a course that reads in a single voice. The build is the test suite, and it deletes its own output if a sanitization check fails, so a bad build cannot be served by accident.
maine-political-map · JavaScript + Leaflet Every Maine political district and 529 town polygons, with 207 officials joined to the districts they hold. Vanilla JS, no build step. Towns are shaded by median household income across classes cut at the data's own quantiles, because even intervals put 80% of Maine in one bucket.
The Response Ledger · JavaScript + Supabase A public record of outreach to government offices and how long each takes to respond. One static page, a free database, and a scheduled job that doubles as its own keepalive. Built entirely on free tiers, which is what drove every architectural decision in it.
Four years in compliance and operations: violation investigations across 1,000+ residential units, vendor negotiation, and staff training on Florida statute. Six Sigma Yellow Belt, Scrum Fundamentals, and a Florida LCAM license. Bilingual English/Spanish.
That background is why the software I build tends to be about process, records, and money that someone has to account for.
