Firebase Development: Authentication, Firestore, Cloud Functions & Hosting
Web and mobile backends on Firebase — sign-in, Firestore data, Cloud Functions, push notifications and hosting — built with security rules and cost control from day one.
A Backend Without Servers, Done Carefully
Firebase lets a product launch without building and running a backend: sign-in, a database that syncs to every device, file storage, push notifications and hosting are all ready to use. The catch is that a Firebase project set up in a hurry becomes expensive and insecure once real users arrive.
We design Firebase backends properly. Firestore collections shaped around how the app reads data, security rules that actually enforce who can see what, Cloud Functions for the logic that must not live in the client, and billing alerts before the first surprise invoice. We also rescue projects that have already hit those problems.
What’s Included
What We Build on Firebase
Authentication
Email, phone, Google, Apple and other sign-in methods, with custom claims for roles and multi-tenant access.
Firestore & Realtime Database
Data models designed for the app’s queries, offline sync, and security rules tested against real scenarios.
Cloud Functions
Server-side logic for payments, emails, data validation, scheduled jobs and third-party API calls that must stay out of the client.
Push Notifications
Firebase Cloud Messaging for iOS, Android and web, with topics, segments and delivery reporting.
Storage & Hosting
Secure file uploads with resized images, and fast global hosting for the web app with preview channels.
Cost & Security Reviews
Read/write patterns audited, indexes fixed, rules tightened and budgets set so a growing user base does not mean a runaway bill.
Benefits
Why Products Are Built on Firebase With Us
- Launch faster: no servers to provision, and authentication and data sync work on day one.
- Security rules written and tested, not left open “until later”.
- Data models chosen with Firestore’s pricing in mind — you pay per read, so structure matters.
- Works with Flutter, React Native, native iOS and Android, and React or Next.js web apps.
- A clear route to move logic to Cloud Run or a traditional backend if the product outgrows Firebase.

FAQ
Firebase Development FAQs
Is Firebase suitable for a serious business application?
Yes, for many. It powers apps with millions of users. The limits are around complex relational queries, heavy reporting and very high write volumes; where those matter we combine Firebase with Cloud SQL or a dedicated backend.
Our Firebase bill has jumped. Can you find out why?
Almost always yes. The usual causes are listeners that re-read whole collections, missing indexes, or a screen that fetches far more documents than it shows. We measure reads per screen, restructure the worst offenders and set budget alerts.
Are our Firestore security rules safe?
Many projects still run with test-mode rules that let anyone read or write everything. We audit the rules, write proper ones for each collection and test them with the Firebase emulator before deploying.
Can you migrate us off Firebase later?
Yes. Because we keep business logic in Cloud Functions rather than scattered through the client, moving it to Cloud Run, Node or Laravel later is a contained job, and Firestore data can be exported in full.
