The Solution

Complete mobile backend - generated.

Push service for iOS and Android, file upload with S3-compatible storage and WebSocket gateway.

Docker Compose setup, Swagger documentation and health check endpoints automatically generated.

View from Lurus Code

Login, files and push meet in real user journeys. Develop interfaces around these flows rather than as a loose collection of endpoints.

The Problem

Mobile App Backend with Push & Auth

JWT auth, refresh tokens and device management are complex and security-critical.
Push notifications (APNs + FCM), file upload and WebSockets require specific expertise.
Docker setup, CI/CD and API documentation are additional efforts that are often forgotten.
