Selected work

These are working demos based on real problems I solved. Some are retroactively updated using AI where it improved the solution since AI wasn't available at the time. Others were left as-is because AI was not the right tool. Not all solutions are optimal using AI.

Each example is a focused slice of a larger project. Proprietary details have been removed and the demos rebuilt for this site.

Product demos

Project 01

Compliance Rules Engine

Decided this needed to be a rules engine, not an AI one, then built a checklist tool that turns a business profile into state-expansion compliance requirements.

Feedback Priority & Sentiment Trends

Built to answer a different question than most feedback tools: not what are customers saying today, but how is sentiment and priority changing over time.

Contract Document Analysis

Turns long contracts into a structured review, risks, missing clauses, and evidence, without replacing the reviewer's judgment.

Image Quality & Duplicate Finder

Large product catalogs collect duplicate and inconsistent images over time, and manually opening every file to check is slow. This brings quality checks, duplicate matches, and a clear recommendation into one place.

Work Style Cart Demo

A weekend take-home cart flow, built manually with no AI-generated code, to show hands-on technical ability under a real deadline.
