I will fix bugs in your flutter or firebase app
Greg Harkins
About this gig
Having trouble with a Flutter or Firebase app? I can help diagnose and fix the issue so you can get back to building.
I work with Flutter, Dart, Firebase, APIs, authentication, databases, Cloud Functions, and web/mobile application development.
I can help with:
Flutter errors and crashes
Firebase configuration issues
Authentication and login problems
Firestore/database bugs
Cloud Functions issues
API integration errors
UI and responsive layout bugs
Build and deployment problems
Logic and state-management issues
Performance and general debugging
Ill investigate the problem, identify the likely cause, implement the agreed fix, and test the affected functionality.
Please message me before ordering if the issue involves multiple systems, several unrelated bugs, a major architecture change, or an unknown/complex problem. I can review the scope and recommend the right package or create a custom offer.
Clear communication and working software are my priorities.

I’m a software developer focused on building practical web and mobile apps for businesses and entrepreneurs. I work with Flutter, Firebase, JavaScript, APIs, cloud functions, databases, authentication, analytics, and automation. I can build MVPs, add features, fix bugs, integrate services, and improve existing applications. I’ve also built and deployed my own full-stack platform, so I understand both the technical work and the business goals behind a project.

FAQ
What do you need from me to get started?
Please send a description of the problem, screenshots or error messages, steps to reproduce it, and access to the relevant source code or project files.
Can you work with an existing Flutter or Firebase project?
Yes. This gig is specifically designed for diagnosing and fixing issues in existing applications.
What if I don't know what is causing the bug?
That's fine. Choose a package that includes investigation, or message me first with the symptoms and I'll help determine the appropriate scope.
Can you fix multiple bugs?
Yes. Standard and Premium packages cover larger scopes, and I can create a custom offer for several unrelated issues.
Can you add new features too?
Yes, but significant new features are usually better handled through a custom offer or a separate development gig.
Should I contact you before ordering?
For simple, clearly defined bugs, you can order directly. For complex problems, multiple systems, or uncertain scope, please message me first.
