Scoremate

Scoremate is a real-time sports scoring and tournament management platform built for organisers running live events. Before Scoremate, tournament directors were managing scores on whiteboards, spreadsheets, and verbal announcements — error-prone, slow, and unscalable.

The core challenge was reliability under pressure. A scoring app that crashes mid-tournament is worse than no app at all. Every architectural decision had to prioritise real-time accuracy and offline resilience — tournaments happen in venues with poor connectivity, so the app needed to work even when the internet didn't.

We built Scoremate as a React Native application with a Node.js WebSocket backend. Scores sync in real-time across all devices on the local network, with a fallback offline mode that queues updates and syncs when connectivity is restored. The admin interface lets organisers manage brackets, schedule matches, and publish results — all from a single screen.
