The Problem

Mobile apps need backends that handle unreliable connections, push notifications, real-time updates, and efficient data transfer — standard REST APIs aren't enough.

Our Solution

We build mobile-optimized backends with WebSocket/Socket.IO for real-time, push notification infrastructure, and offline-first sync strategies.

What You Get

Real-Time

WebSocket connections for instant updates

Push Notifications

FCM + APNs integration for both platforms

Offline-First

Local-first data sync for unreliable connections

Efficient

Optimized payloads and pagination for mobile

Frequently Asked Questions

Do I need a separate mobile backend?

Not necessarily. We can add mobile-specific features (real-time, push) to your existing API. A separate service is only needed for complex real-time requirements.

Socket.IO or WebSockets?

Socket.IO for most cases — it handles reconnection, rooms, and fallbacks automatically. Raw WebSockets only for very specific performance needs.

How do offline sync and conflict resolution work?

We implement last-write-wins or timestamp-based resolution depending on your data model. The client queues changes offline and syncs when connected.

Can you integrate with Firebase?

Yes. We use Firebase for push notifications and can integrate Firestore for real-time sync if your use case benefits from it.
