I will fix your firebase, firestore and javascript bugs in 48 hours
Gabriel Renaud
About this gig
Is a Firebase or JavaScript bug stopping your app? Login that fails, Firestore data that won't save, Cloud Functions that error out, a page that breaks on one phone. Send me the problem and I will find the cause and fix it.
I work with AI coding tools (Claude) to find problems faster, and I check every fix myself by running your code before I deliver. I built LFG, a Firebase app with AI and Maps, and fixed bugs like failed uploads and blocked images in it.
WHAT I FIX
- Firebase Auth, Firestore, Storage and Cloud Functions errors
- JavaScript, Node.js, React and PWA bugs
- Security rules that block the wrong users
- Broken forms, queries, uploads and notifications
- Apps built with Lovable, Cursor, Bolt or other AI tools that stopped working
HOW IT WORKS
- Tell me what happens, what you expected, and share the repo or the code files
- I reproduce the bug and send you the cause
- I fix it and deliver the changed code with a short explanation
A "bug" is one specific problem with one clear expected result. New features are not bugs: message me and I will quote them.
Spanish or English, no problem.

I'm Gabriel, a Latino founder who builds web apps people install and use. My own product, LFG - Latino Foodie Guide, is a bilingual Firebase PWA, now in private beta: AI assistant, Google Maps directory, private chat, orders with live stock, ratings with anti-fraud rules and 390 automated tests.
I also run an import company, so I think like an owner: clear scope, fixed quotes, weekly demos and security from day one.
Calls in English or Spanish. Tell me what your users need and I'll turn it into an app.

FAQ
How do I send you my code?
Through Fiverr: attach a zip or share a repository as a read-only collaborator. I never need your passwords; if I need Firebase access, I will guide you to add me as a Viewer.
What counts as one bug?
One specific problem with one clear expected result, for example "login fails with Google on iPhone". Two different symptoms with different causes count as two bugs.
What if you cannot fix it?
I tell you in the first message after reproducing it. If it is outside what I can fix in this gig, I tell you why and you can cancel without paying for work not done.
Do you add new features?
No. New features and redesigns are quoted separately with a custom offer, so the price stays clear.
Do you use AI?
Yes, AI tools such as Claude help me find causes faster. I test every fix on your code before delivering and I am responsible for the result.
