Software engineer · Rochester, NY

I've been building software for about 15 years. The first 12 were spent doing integration consulting at banks, healthcare companies, and large enterprises.

Lately, I've been working on my own products, PlankeApp and Greener Closet. I build them by creating systems and workflows for my AI agents (Claude Code, Codex, Cursor, Grokbot).

Projects

  • The hiring marketplace for the Pilates industry. Over 4,000 studios and instructors use it to find each other, and about 90 studio organizations pay for it. I built the iPhone and Android apps, the website, and the billing that keeps Stripe, Apple and Google in agreement.

  • Scores clothing 0-100 on six factors I researched - microplastics, PFAS, dyes, and more. Paste a link, get a score. Over 3,300 products scored so far, and it can now read a photo of a clothing tag.

  • Ask ChatGPT if that sweater is mostly plastic and it checks Greener Closet for you. Built as an MCP server, so other AI assistants can use it too. There's also a Chrome extension that scores clothes on any store you shop.
