I will fix bugs or add features to your react, typescript, or firebase app
Eli H.
Sobre este Serviço
Something broken in your React or Firebase app, or a feature you need added? I fix bugs and add features to existing React, TypeScript, and Firebase apps, working in your code and keeping your structure.
What I fix:
- Crashes, blank screens, and console errors
- TypeScript and build errors
- Broken forms, buttons, and page flows
- Firestore queries, security rules, and data that won't save or load
- Login and auth problems
- Layout and responsive issues in React and Tailwind CSS
What I add:
- A new screen, form, or filter
- Search, sorting, or CSV export
- Role-based access for an existing login
- New fields and data in Firestore
How it works: message me first with your repo or the error details. I check the problem, confirm the package or send a custom offer, fix it, test it, and explain what I changed.
Every order includes:
- Bug investigation and root-cause notes
- Tested fix delivered to your repo or as files
- Detailed code comments where needed
You work directly with me, the developer. Building a new app from scratch? That is a separate gig of mine.

Idiomas
Inglês
I build custom software systems that automate business operations and replace manual workflows. My work goes beyond basic websites — I create full platforms, internal tools, and integrations that improve efficiency and reduce costs. I specialize in structuring messy, real-world processes into reliable systems, including data sync, automation, and multi-platform integrations. The goal is simple: build solutions that save time, reduce errors, and scale operations without adding overhead.

Perguntas frequentes
Can you look at my code before I order?
Yes, please do. Message me with your repo (or a zip), the error message or screenshots, and the steps to reproduce it. I will confirm which package fits, or send a custom offer, before you pay anything.
What counts as one bug?
One problem with one cause, for example a crash, a console error, a broken form, a wrong Firestore query, or a layout issue on one screen. If what looks like one bug turns out to be several, I will tell you before doing extra work.
What if you cannot fix it?
If I cannot find the cause or fix the bug as agreed, I will explain what I found and we can cancel the order through Fiverr. I would rather check first, which is why I ask you to message me before ordering.
How will I get the fix?
As a pull request or commits to a branch in your repo, or as updated files if you do not use Git. Each delivery includes short notes on what caused the bug and what I changed.
Can you build a whole new app instead?
This gig is for existing apps: bug fixes and features added to code you already have. For a new custom app, dashboard, or portal built from scratch, see my custom web app gig.
