Things I've built

Run your business from a prompt — with a governor in the middle. A natural-language front end that provisions and revokes real access across an identity provider, an ITSM platform, and a data warehouse. The core is a decision engine that evaluates every requested entitlement against cost and sensitivity rules and returns auto-approve, flag, or deny — so the agent only executes what policy already allows, and a human sees the rest. Every action lands in a hash-chained audit log that can be verified end to end. It also catches agent overreach: when the agent asks for more than the task needs, the request is held for approval and the payload withheld.

A members-only school directory for the Tewksbury Township (NJ) PTA. I designed it around two kinds of users. Parents mostly look someone up on a phone, so the directory is search and filter by child, grade or teacher, with one-tap call, email and "add to contacts." The admins are volunteers and the board changes every year, so the admin side opens on one question: what do you need to do? Each job is a short, guided path, not a page of settings. Starting a new school year is four steps.

Privacy is part of the design: each family chooses Yes or No for every detail, only paid members can sign in, and the security rules on the database enforce it rather than the page. It ships with picture guides, a one-step undo for admin changes, and a handover document a new board can give to an AI assistant. It runs on Firebase's free plan with 129 automated tests, and has been in use since October 2026.

Screenshots use made-up families, not real member data.

Membership running on software instead of a spreadsheet. A member-management portal for the Central Jersey Corvette Club, which has 82 members and 100 Corvettes. It runs the roster, member and car records, dues and reminders, reports, member email, and an audit trail of admin actions. Its users are volunteer officers, not IT people, so the design keeps one meaning per color and label everywhere. A dashboard answers the questions officers actually ask: who's paid, who's past due, and what's in the garage.

Running it in production shaped the features. Removing a member moves them to a Former Members archive they can be reinstated from, rather than deleting them. A roster re-import updates existing members instead of duplicating them. Treasurers get their own role. I ship it in versioned releases with an illustrated admin guide, error capture, and 224 automated checks run before every upload.

Screenshots are the live portal, with every member's name, phone, email and date replaced by made-up ones.
