Firebase Problems and Their Fixes

A data model built for 100 users meets 10,000. Five problems come up.

Week One Ends With a Report

Money first. Your team keeps shipping while I read.

You Borrow Scars I Already Earned

Ranked findings, each with its fix. These four I have already paid for.

Who It's For

Teams with a Firebase web app and no one who owns it.

Right For

Better Elsewhere

How It Works

A simple, predictable and transparent process that eliminates development headaches.

1

Pay once; a task board opens, and you add me to the Firebase project, billing and repo.

2

Setup

Work starts the next working day. Everything stays in your accounts.

3

Plan & Develop

After the report you rank the fixes; if you keep me on, I take one at a time.

4

Review & Refine

Every change goes up for your review. I revise until you're satisfied.

5

Progress

You approve finished work. I move to the next fix, then to features.

6

Maintain

You report issues anytime; I handle them first.

FAQ

Usually reads, not traffic: whole-collection listeners, rules that look up other documents, polling. On my own app, fixing those took the Firestore bill from about $12 to under $1 a month.

Partly: budget alerts only warn, and Firestore has no spend cap. The report lists the limits your app needs.

A security rules review asks one question: can a signed-in stranger read or write what they shouldn't? Rules usually fail three ways: left open from setup, a sign-in-only check, or a collection added later.

Not on its own: Firebase web keys are public by design. An OpenAI or Gemini key in the browser is, so those calls move behind Cloud Functions.

Sometimes: Postgres fits heavily relational data better. More often the data model changes and the platform stays.

Yes, by the week: fixes, then features on Firestore, Auth, Cloud Functions and Hosting, on my default stack.

I revise the report until you're satisfied. Kept on by the week, cancel anytime with no penalty.

Fill in the project form with what moved: the bill, a Google rules email or a slow screen. I reply the next working day.
