Flutter App Fixes & Enhancements

I need a detail-oriented Flutter developer to step into an existing codebase for my mobile app, Control Check, and deliver a handful of clean, dependable improvements.

The focus areas are:
• UI/UX design tweaks
• API integration work
• Bug fixes and overall performance tuning

On the API side specifically, you’ll be:
• Integrating one new endpoint
• Repairing a few broken calls
• Streamlining response handling to boost performance

What I expect from you:
• A quick code review to spot problem areas
• Precise fixes that compile and run flawlessly on both Android and iOS
• Responsive layouts that hold up across common screen sizes
• Clear, well-commented commits so I can follow every change

Acceptance criteria
• All listed issues are resolved with no new regressions
• Builds pass on Android & iOS emulators and at least one physical device each
• New and existing API calls return correct data within agreed performance thresholds
• A short handover note summarising what was changed and any follow-up recommendations

If this fits your skill set, let me know your availability and share a couple of examples where you have maintained or rescued another Flutter project.
