The Challenge

A poker club running a season-long tournament was tracking attendance, per-event scores, and standings across spreadsheets and WhatsApp. They needed a single, members-only app with a live best-of-N leaderboard, event registration, and an admin toolset — all in their own timezone.

What We Built

A cross-platform mobile app (iOS & Android) on a scalable cloud backend with real-time push notifications. Separate member and admin experiences, timezone-aware event windows, secure token auth, and a flexible UI so content and rules change without an app release.

Key Features

  • Live tournament leaderboard with podium and best-of-N scoring
  • Event registration with attendance confirmation and timezone-aware open/cutoff windows
