I will integrate backend into your unity game


About this gig
Does your Unity game need a backend but you don't know where to start?
Authentication, leaderboards, cloud save, matchmaking, real-time databases backend is where most indie developers get stuck. I bridge the gap between your Unity game and a scalable cloud infrastructure.
I integrate Firebase, AWS GameLift, MySQL, PostgreSQL, and MongoDB with Unity building systems that are secure, scalable, and actually maintainable as your game grows.
What I integrate:
- Firebase Authentication (email, Google, anonymous)
- Firestore / Realtime Database for cloud save and leaderboards
- AWS GameLift for multiplayer session management
- MySQL / PostgreSQL for structured game data
- MongoDB for flexible player data storage
- REST API integration with Unity (GET, POST, PUT, DELETE)
All deliverables include:
- Full C# Unity-side source code
- Backend configuration and setup guide
- Basic security implementation
- Documentation
- 1 round of revisions
Premium includes architecture design, full deployment, and 30 days of post-delivery support.
Message me before ordering backend scope varies a lot and I want to quote you accurately.
