June 2023 – November 2023
Context
Design and development of a full sports-betting platform around a Super Bowl–style event.
The ecosystem includes three interconnected applications:
- A web app for users
- A mobile app for browsing
- A desktop app (Electron) for admins and commentators
The goal was a coherent system to manage matches, bets and payouts in real time.
Challenge
Real-time sports betting involves several technical and functional constraints:
- Data sync across multiple apps (web, mobile, desktop)
- Secure user and transaction handling (authentication, JWT)
- Dynamic payout calculation based on match results
- System reliability when matches close
- Clear data visualization (history, wins, losses)
We needed a robust architecture to centralize business logic while feeding multiple interfaces.
Objective / solution
Design a complete, scalable platform to:
Bet in real time on multiple matches
Centralize business logic through a secure REST API
Power multiple interfaces (web, mobile, desktop)
Automatically calculate user payouts
Deliver a smooth, consistent experience on every device
