Full-Stack Developer · I build real-time web apps

Open to full-time roles LinkedIn Portfolio Email

I build full-stack products end to end, from database schema and API design to the UI, tests and deployment. I'm most interested in software people use together in real time: collaborative editors, live scoreboards and team workspaces. I care about shipping things that are secure, tested and actually running in production.

Featured work

Pickleball tournament manager app

Pickleball · real-time tournament manager

Replaces paper scoresheets for my group's pickleball sessions: every score syncs live to every phone at the court.

  • Live sync across all devices with Firebase Realtime Database: spectators join with a code or link, with a live viewer count and offline detection
  • Fair scheduling for 4–20 players: round-robin that prioritises new partners and opponents, rotating byes for odd counts, and playoff brackets chosen automatically by player count
  • Player profiles with Google Sign-In, career stats, badges, head-to-head records and clubs
  • Access control for creators, scorers (PIN), spectators and guests; installable as an app (PWA) with push notifications
