01.About

I'm a software developer based in Flanders, NJ. I spent nearly six years at ADP as a Senior Application Developer, building and debugging complex applications that businesses depended on every single week to pay their people.

These days I'm at LeaguePals, building software for the bowling world — and on the side I design and ship my own products, like an iPad app that runs tournament bracket side pots with a matchup-minimizing algorithm I built from scratch.

I care about software that holds up under real use: tested before it ships, fast where it counts, and simple enough that the next developer says thanks.

03.Things I've Built

Pay the Dragon

Invoicing with automatic reminders for freelancers and small businesses — send the invoice, the dragon does the nagging. Clients get a hosted invoice page with one-tap card payment through Stripe Connect, so money lands directly in the freelancer's own Stripe account and the platform never holds funds. A daily idempotent cron sends polite email reminders before and after the due date until the invoice is paid, with open tracking and a full activity timeline. Rebuilt from my 2018 bootcamp capstone and shipped in a day.

  • TypeScript
  • Drizzle

Jukeboard

Live song-request platform for weddings and events. Guests scan a QR code at their table to search real songs and build the queue together, while the DJ and couple moderate in real time — dedupe-to-upvote requests, a do-not-play list, a must-play setlist, printable QR table cards, and Google/Apple sign-in. Real-time updates over Server-Sent Events.

  • Next.js
  • TypeScript
  • Postgres
  • Vercel

Bowling Side Action (App)

iPad app for running side pots at bowling leagues and tournaments — brackets, eliminators, high game pots, sweepers, and mystery doubles with live payout math. A custom algorithm distributes entries into 8- and 16-person brackets while minimizing duplicate matchups. Live on the App Store.
