Firebase cloud backend for your app and website
We build the part nobody sees: user accounts, database, server functions and push notifications, with security rules so everyone sees only their own data.
A business app or website needs a safe place where the data lives: who each user is, what they can see and what happens when someone pays, records a sale or sends a notice. That is the backend, and if it fails, everything else fails.
We build it on Firebase: Authentication for accounts, Firestore as the database, Cloud Functions for logic that must not live on the phone (payments, invoice numbers, permissions) and Cloud Messaging for push notifications. It is the same backend behind Minkay, Kipuy, Masy and Codea.
What's included
User accounts
Sign in with email, Google or Apple, with roles (for example admin, staff or customer) and per-role permissions.
Per-record security rules
Firestore rules covered by tests: each user reads and writes only what belongs to them.
Server functions
Cloud Functions for sensitive work: payment amounts, payment webhooks, receipt numbering and scheduled jobs.
Push notifications
Android and iOS notifications when it matters: a payment received, an announcement or a reminder.
One backend for app and web
The mobile app and the web dashboard read the same data with the same rules: nothing is copied by hand.
Backups and separate environments
Separate test and production projects, plus database backups.
What we build it with
Firebase Authentication
Accounts with email, Google or Apple.
Cloud Firestore
Real-time database with security rules.
Cloud Functions
Server logic, webhooks and scheduled jobs.
Cloud Messaging
Push notifications for Android and iOS.

Five layers, like a terrace
Each layer holds up the next. Timelines depend on the scope and we confirm them in the proposal.
Layer 1
Discovery
First conversation, free
We learn the process that takes your time today (the spreadsheet, the notebook or the WhatsApp group) and define a small scope with a clear timeline and cost.
Layer 2
Design
Before coding
We sketch the screens and the main flow so you see how your software will work before we build it.
Layer 3
Development
In short stages
We build in deliveries, with versions you try on your phone or browser and adjust with us.
Layer 4
Launch
When the scope is done
We publish to Google Play, the App Store and servers, ready for your users.
Layer 5
Support
After launch
We stay with you with fixes, improvements and new versions, just like we do with our own apps.
Frequently asked questions
What is a backend and why do I need one?
It is the part of your system that lives in the cloud: it stores the data, checks who each user is and runs sensitive logic such as payments. Without a backend, information stays on each phone and cannot be shared with your team or protected.
Why Firebase?
Because it already handles accounts, a real-time database, functions and push notifications with solid security, and you pay for what you use. That lets you launch sooner and spend little while your app grows.
Is my data safe?
We write security rules for every collection and test them: each user sees only their own data. Sensitive values, such as payment amounts, are computed on the server, not on the phone.
Can you connect the backend to my current app or website?
Yes, as long as your app or site can talk to external services. In the first conversation we review what you have and tell you what is worth reusing.
