About this Gig
Is your Flutter app broken, outdated, or missing a feature?
I'm a Flutter developer with 5+ years of experience and 4 published apps (UDealZone, Perfumoto, My Lava, MapX). I fix and improve existing apps, including code written by other developers.
What I can do:
- Fix bugs, crashes, null errors and UI overflow issues
- Upgrade to the latest Flutter/Dart and fix deprecated packages
- Fix Gradle, CocoaPods and build errors
- Add features: login, payments, push notifications, maps, chat, APIs
- Firebase setup and fixes (Auth, Firestore, FCM)
- Improve performance and clean up messy code
I work with: GetX, Provider, Bloc, Riverpod, REST APIs, Firebase, Supabase.
How it works: share your code (GitHub or zip) and what you need. I review it, confirm the price and timeline, then deliver tested, updated source code with a short change log.
Please message me before ordering so I can check your code and give an accurate quote.

FAQ
Can you work on code written by another developer?
Yes. Most of my maintenance work is on apps built by other developers. I review the code first and tell you honestly what needs fixing before you pay.
How do I share my code with you?
Invite me to your GitHub, GitLab or Bitbucket repo, or send a zip of the project. Please include any Firebase or API setup notes so I can run the app.
My app stopped building after a Flutter update. Can you fix it?
Yes. I upgrade Flutter/Dart, replace deprecated packages and fix Gradle, Kotlin and CocoaPods errors so the app builds and runs on Android and iOS again.
What if the bug is bigger than expected?
I always review the code before you order. If a fix needs more work than the package covers, I will send a custom offer first. No surprise charges.
Will you sign an NDA?
Yes. I am happy to sign an NDA before you share your code. Your code and idea stay confidential.
