I will build scalable realtime backend services using websockets
M.Afzaal
About this gig
Struggling with high latency or dropped connections? Real-time apps need bulletproof architecture. I'm Afzaal, a Solutions Architect & Backend Engineer with 7+ years of experience building high-volume WebSocket systems for Web2, Web3, and multiplayer gaming.
Whether you need live notifications, a multiplayer bridge, or a real-time dashboard, I build bidirectional WebSocket services that won't fail under pressure.
What I Offer:
- Protocols: Expert implementation of native WebSockets (ws) & Socket.io.
- Frameworks: Robust Node.js (ES6) or .NET Core servers.
- Routing: Isolated rooms, namespaces & private channels.
- Horizontal Scaling: Redis Pub/Sub integration to sync events across servers, handling thousands of concurrent users without lag.
- Integration: APIs & JS bridge libraries for Web, Mobile & Unity (WebGL).
- Deployment: Load-balanced AWS cloud setups.
Why Choose Me?
- Architect-Level: Former Gaming Solutions Architect.
- Proven: Deep experience with Unity WebGL bridges & socket communication.
- Certified: Google Cloud & Architecture certified.
- Introductory rates applied! Message me before ordering to discuss your project.

FAQ
Do you use Node.js or .NET Core for WebSockets?
I am highly proficient in both. I can implement Socket.io or the native ws library for Node.js environments, or native SignalR in .NET Core, depending on your existing tech stack.
Q: How do you handle scaling for thousands of concurrent WebSocket connections?
Standard WebSockets are stateful, making them tricky to scale. I utilize Redis Pub/Sub as a message broker to synchronize state across multiple load-balanced server instances. This ensures that a user connected to Server A can seamlessly chat or interact with a user connected to Server B.
Can you secure the WebSocket connection?
Absolutely. I implement strict authentication protocols (like JWT validation during the initial WebSocket handshake) to ensure that only authorized users can establish a connection and subscribe to specific data channels.
I have a Unity WebGL game. Can you connect it to a Node.js WebSocket server?
Yes! I have specific, hands-on experience building custom JS bridge libraries that allow Unity WebGL builds to communicate flawlessly with Socket.io/WebSocket backends.
