Firebase Development for Apps That Need to Move Fast.

We design and build Firebase backends for Flutter and web apps: data models that stay fast at scale, Cloud Functions that hold your business logic, and security rules you can trust.

What We Do

Firebase Development Services

Firestore Data Modelling

Collections, indexes and denormalisation planned around how your app reads data, so queries stay fast and bills stay predictable.

Cloud Functions in TypeScript

Business logic, webhooks, scheduled jobs and third-party integrations in typed, tested Cloud Functions.

Auth & Security Rules

Firebase Authentication with email, social and phone sign-in, plus security rules tested against every role.

Push Notifications (FCM)

Real-time alerts through Firebase Cloud Messaging, targeted and timed so users keep them switched on.

Analytics & Crashlytics

Analytics events, Crashlytics and Remote Config set up from launch, so every release can be measured.

Firebase Audits & Cost Fixes

Reviews of existing Firebase projects for read-heavy queries, rule gaps and runaway costs, with a fix plan.

How the work runs

Firebase Backends Built for Production

Firebase gets a product live quickly, but the early decisions, such as data shape, rules and function boundaries, decide whether it still works at ten thousand daily users. We make those calls on purpose, up front.

If your product needs relational data, complex reporting or SQL, we will tell you, and Supabase may be the better fit.

Data model first

Reads, writes and indexes are planned before screens are built, which keeps Firestore costs flat as usage grows.

Typed Cloud Functions

TypeScript, shared types with the app and tests, so backend changes do not break clients silently.

Rules that are tested

Security rules are covered by emulator tests for every role, not left in test mode.

Monitored from day one

Crashlytics, alerts and budget limits configured before launch, not after the first incident.

Tech Stack

Firebase technology stack

Firebase with Firestore, Auth, Cloud Functions and FCM, a Flutter client, and Node.js or Python services where a workload outgrows Functions.

Firebase Development FAQ

For most early-stage mobile apps, yes. Firebase gives you auth, a real-time database, functions, push and analytics without running servers, which gets an MVP live faster.

Yes, if the data model and queries are designed for it. UpAlerts, a Flutter app we built on Firebase, serves 10,000 daily active users.

Yes. We write Cloud Functions in TypeScript with shared types and tests, which makes backend changes safer for both the app and the functions.

Often. Most high Firebase bills come from unbounded reads, missing indexes or chatty listeners. We audit usage and fix the queries that cost the most.

Firebase suits real-time, document-shaped mobile apps that need to ship quickly. Supabase suits products with relational data, SQL reporting or a need to avoid lock-in. We help you choose before you build.
