Mobile App Backend Development

High-performance backends for iOS, Android, and cross-platform mobile apps — real-time sync, push notifications, and offline-first design.

Mobile apps need backends that are fast, reliable, and handle the unique challenges of mobile — intermittent connectivity, push notifications, real-time data sync, and efficient battery/bandwidth usage.

We build mobile backends that deliver instant data to your app, handle offline scenarios gracefully, and scale to millions of users. Whether you're using React Native, Flutter, Swift, or Kotlin, we build the server-side to match.

Our mobile backend architecture includes efficient pagination, delta sync for bandwidth optimization, background job processing, and CDN-backed media delivery.

What's Included

Real-Time Sync

WebSocket and SSE-based real-time data synchronization for chat, collaboration, feeds, and live updates.

Push Notifications

APNs and FCM integration with segmentation, scheduling, rich notifications, and delivery analytics.

Authentication

Social login (Google, Apple, Facebook), biometric auth, device-based sessions, and secure token management.

Offline-First

Conflict resolution, delta sync, queue-based uploads, and local-first architecture for unreliable connections.

Media Pipeline

Image/video upload, processing, optimization, CDN delivery, and presigned URL generation for direct-to-S3 uploads.
