Your mobile app needs a backend. User accounts, data storage, push notifications, real-time updates — that's what we build. We've built backends for 12+ mobile apps, including the Workiley Android app (10,000+ downloads). Our backends handle 50,000+ daily API requests with average response times under 150ms.
A good backend is invisible. It just works. Users sign up, data syncs, notifications arrive. That's our job. You focus on your app's frontend and user experience. We handle the server.

Every backend we build includes these core components
Email/password, social login (Google, Facebook, Apple). JWT tokens for secure API access. Password reset flows. Account management endpoints.
User profiles, app data, settings. Proper indexing for fast queries. Offline sync support. Data validation and sanitization.
Firebase Cloud Messaging (FCM) for Android. APNs for iOS. Targeted notifications, scheduled messages, read receipts.
User avatars, images, documents. Upload to cloud storage (AWS S3, DigitalOcean Spaces). Compression and optimizations.
WebSockets or Firebase Realtime. Live chat, activity feeds, location tracking, collaborative features.
User activity tracking. Error logging. Performance monitoring. You'll know exactly what's happening.
Choosing the right stack for your scale and budget
Our primary choice for most backends. Eloquent ORM, built-in authentication, queues for notifications, task scheduling, API resources. Perfect for 90% of apps. Handles millions of requests with proper caching.
Event-driven, non-blocking I/O. Great for real-time features, chat apps, live dashboards. Lower memory footprint. Good for apps with many concurrent connections.
Serverless backend. Fast setup, auto-scaling. Great for MVPs and smaller apps. Less control but faster development. We can build on these and migrate later if needed.
We deploy on AWS, DigitalOcean, or Linode. Auto-scaling, load balancers, CDN, database replication. Your backend grows with your user base.
From job portals to social apps
Stack: Laravel + MySQL + Redis + FCM
Features: User auth (job seekers + employers), job posting API, application tracking, push notifications for new jobs, saved searches, admin dashboard.
Scale: 10,000+ app downloads, 50,000+ daily API requests. Average response: 120ms.
Client quote: "The backend has been rock solid for 18 months. Zero downtime."
Stack: Laravel + Stripe + PostgreSQL
Features: Product catalog API, shopping cart, order management, payment processing, inventory tracking, order status push notifications.
Scale: 5,000+ monthly active users. Processes $50k+ in transactions monthly.
Result: Client launched iOS and Android apps using the same backend.
Stack: Node.js + Socket.io + MongoDB
Features: Real-time messaging, read receipts, typing indicators, file sharing, group chats, push notifications.
Scale: Handles 500+ concurrent users with 50ms latency. Message delivery guaranteed even with spotty connections.
Stack: Laravel + MySQL + Redis + WebSockets
Features: User workouts, progress tracking, social feed, challenges, leaderboards, scheduled notifications.
Result: 3,000+ daily active users. Syncs workout data across devices instantly.
One backend, multiple frontends: Every API we build works with Android (Java/Kotlin), iOS (Swift), Flutter, React Native, and web apps. You're not locked into one platform.
A process designed for mobile developers
What data does your app need? What actions will users take? We map every endpoint before coding.
Tables, relationships, indexes. We design for fast queries and future growth.
RESTful endpoints. Authentication. Rate limiting. Input validation. Error handling.
FCM + APNs setup. Device token management. Targeted notification logic.
Postman collection or Swagger/OpenAPI. Your mobile developer will love this.
We deploy to your cloud account. Set up monitoring, backups, auto-scaling.
We've built Android and Flutter apps ourselves. We know what mobile developers need from an API — efficient payloads, offline support, minimal round trips, proper error codes.
Our backends handle growth. From 100 users to 100,000. We design database indexes, caching strategies, and load balancers from day one.
JWT tokens, HTTPS enforced, SQL injection protection, rate limiting, DDoS mitigation, regular security updates. We take this seriously.
Your mobile developer gets a complete API reference with examples. No guessing. No "it worked on my machine."
Every app is different. Here are ballpark ranges.
$1,500 – $3,500
Best for MVPs and simple apps. Fast setup. No server management. 2-4 weeks. Scales to 50k users easily.
Get quote →$4,000 – $10,000
Laravel or Node.js. Full control. User auth, database, push notifications, admin panel. 4-8 weeks. Handles millions of users.
Get quote →$8,000 – $18,000+
Real-time features (chat, live location, gaming). WebSockets. High concurrency. 6-12 weeks.
Get quote →💰 Ongoing costs: Server hosting ($50-300/month depending on traffic). Push notification send costs (Firebase is free up to huge volumes). We'll help you estimate before we start.
🔧 Monthly maintenance: $197/month includes security updates, monitoring, backups, and up to 2 hours of changes.
Firebase is great for getting started. But it gets expensive at scale ($0.06 per 100k reads adds up). Custom backends have higher upfront cost but lower ongoing costs past ~50k users. We'll help you decide based on your growth projections.
Absolutely. We coordinate with your frontend developer, share Postman collections, and answer questions. Many of our clients have their own mobile devs but outsource the backend to us.
Simple CRUD backend (user profiles, content feed): 3-4 weeks. Full-featured backend (auth, social features, notifications, payments): 6-10 weeks. Real-time apps: 8-12 weeks.
Yes! We offer mobile app development services for Android and Flutter. Many clients get both backend + app from us at a discounted bundle price.
We design for scale from day one. Database indexes, caching, queue workers, load balancers. If you suddenly get 100x traffic, we help you scale up within hours, not days.
Yes — complete OpenAPI/Swagger documentation or Postman collection. Your mobile developer will know exactly how to call every endpoint.
Let's talk about your app idea. We'll recommend the right backend architecture, give you a fixed price, and show you similar projects we've built.
