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.
