What the backend does for your app
The app on the phone is the tip of the iceberg. Accounts, data storage, business logic, notifications, and anything shared between users lives on the server. We build that backend as a clean API your app talks to.
- User accounts, authentication, and session management
- REST or GraphQL endpoints tailored to your app's screens
- Data storage and the business logic behind each feature
- Push notifications (APNs for iOS, FCM for Android)
- File and image upload, storage, and delivery
- Third-party integrations (payments, maps, analytics) handled server-side
Built for mobile realities
Mobile backends have constraints web apps don't — flaky connections, battery and data limits, app-store review, and multiple app versions live at once. We design the API around those realities so the app stays fast and doesn't break on the next release.
- API versioning so old app versions keep working after you ship updates
- Efficient, minimal payloads to save users' data and battery
- Offline-friendly patterns and graceful handling of dropped connections
- Pagination and caching so lists load fast
- Secure token-based auth (OAuth/JWT) built for mobile
- Rate limiting and abuse protection on public endpoints
Infrastructure and scale
We host the backend on infrastructure sized to your stage — no need to pay for enterprise scale on day one — with a clear path to grow. And we build it so you, or the next developer, can maintain it.
- Cloud hosting (AWS, Google Cloud, or similar) sized to your traffic
- Managed databases with backups and monitoring
- CI/CD so backend updates ship safely
- Logging and error tracking to catch issues in production
- Documentation so your app team (or a future one) can build against it
- Room to scale without a rewrite as your user base grows

Frequently asked questions
We already have the app designed — can you build just the backend?
Yes, that's a common request. We build the API and infrastructure to match your app's screens and data needs, and give your mobile developers documented endpoints to build against. We can work from your designs or an existing frontend.
REST or GraphQL?
Both work; the right one depends on your app. REST is simple and universally supported; GraphQL shines when screens need flexible, nested data and you want to avoid over-fetching. We'll recommend based on your app's data patterns, not a trend.
How do we handle old app versions after we update the backend?
With API versioning. Because users don't all update at once, we version endpoints so an older app keeps working while new features roll out. Planning for this up front avoids the classic 'we broke everyone on the old version' incident.
