You will get integration playfab, firebase or custom backend in unity
Project details
Need a stable backend for your Unity game?
I implement and fix backend integrations including PlayFab, Firebase, Node.js servers, and REST APIs.
I handle:
Authentication systems
Leaderboards and player data
Cloud functions and server logic
Multiplayer state handling
API integration (FastAPI / .NET / Node.js)
Deployment to AWS or Azure
Most Unity developers only build gameplay. I build the full client-server architecture.
If your backend is unstable, slow, or poorly structured, I can redesign and stabilize it properly.
Message me before ordering.

Unity Multiplayer & Backend Architect | PlayFab, Node.js, Azure, AWS
Dubai, United Arab Emirates - 2:38 pm local time
With over 12 years of software engineering experience and 6+ years working with Unity, I specialize in building production-ready mobile and online games that require more than just gameplay mechanics. My focus is on backend integration, real-time systems, LiveOps infrastructure, and long-term scalability.
Unlike typical Unity freelancers who only develop front-end gameplay, I handle the complete technical architecture — from Unity client to backend APIs to cloud deployment.
My experience includes:
• Multiplayer game servers built with Node.js
• REST APIs using FastAPI and .NET
• PlayFab backend integration and customization
• Azure Functions and AWS cloud infrastructure
• Game server deployment and DevOps configuration
• Backend-connected mobile games
• VR applications using HTC Vive
• Real-time data-driven features and cloud-based systems
I have delivered more than 20 applications and games, including mobile multiplayer titles, VR projects, and backend-powered production systems.
If your project requires:
• Multiplayer synchronization and server architecture
• Backend integration (PlayFab, custom APIs)
• Scalable cloud deployment (AWS / Azure)
• LiveOps-ready infrastructure
• Fixing unstable or poorly designed game systems
I can design and implement the full technical solution — from prototype to production.
