I build and fix Firebase backends for mobile and web apps — authentication, Firestore and Realtime Database structure, cloud functions, push notifications and security rules. Firebase powers every production app listed on this site.
If more than one of these sounds familiar, this is the right page.
Firebase gets products to market quickly and then bites when the data model was never designed. The usual symptoms are a bill that grows faster than the user count, security rules that allow more than anyone realises, and queries that need data restructured to work at all.
I design Firebase backends around how the app actually reads data, write security rules that are tested rather than assumed, and keep realtime features from turning into a runaway read bill.
The order matters — each step exists because skipping it causes a specific, predictable problem later.
Firebase costs and performance are set by how you read, not how you write. We start by listing every query the app actually needs.
Structure collections and documents around those reads, including where denormalising is the correct trade rather than a shortcut.
Authentication providers and security rules written against the data model and tested with the emulator, so access is verified rather than assumed.
Cloud Functions for anything the client must not be trusted with, and push notification delivery wired and tested on real devices.
Identify the expensive read paths, add caching and pagination where they pay off, and leave you with the monitoring to see it.
Live products using the same stack — not mockups.

Read the case studyarrow_forwardFirestore for most apps — richer queries and better scaling. Realtime Database still wins for high-frequency, small-payload updates such as live presence or cursor positions. Some apps use both, deliberately, for different data.
Almost always reads, not storage — usually a screen fetching a whole collection when it needs a page of it, a listener that never detaches, or a structure that forces the client to over-fetch and filter locally. These are findable and fixable, and the audit step exists to find them.
Yes, to Postgres with Prisma, which is the stack this site runs on. It is worth doing when your queries have outgrown what Firestore does well. It is not worth doing just because the bill is high — that is usually a data-model problem that follows you to the new database.
Only if they have been tested. Rules that look right frequently allow reads nobody intended, and the default state of a new project is permissive. I test rules against the emulator with cases that should pass and cases that must fail.
Tell me what you're building and what's in the way. If I'm not the right person for it, I'll say so and point you somewhere better.
