Mobile App Maintenance

@onkarkulkarni8

Hi, I checked your "Mobile App Maintenance" project description, it looks like the focus is on delivering a clean, responsive website that works well across all devices. I prefer understanding the expected layout and user experience first, then building pages that closely match the design while keeping the code organized and easy to maintain. Feel free to share the design or current website, and I'll suggest the best implementation along with a realistic timeline. Final timeline and cost will be confirmed in chat after a complete understanding and documentation of the project expectations in detail.

The first pass will compare Firebase Performance cold-start and screen-transition traces with a mid-range device run, then trace the slow path through React Native renders and the Swift/Kotlin module boundaries. I’ll profile startup and navigation, remove avoidable work or retained references, and verify each change with before/after timings rather than broad rewrites. I’ll work in a branch, preserve the existing CI tests, and submit a focused pull request with clear commits, the requested metrics, and maintenance recommendations. The complete optimization pass, PR, and brief report will be delivered in 2 days. Is a representative mid-range device already available for validation, or should I use the model most prominent in Firebase Performance data? Muhammad Saad

Hi, I am Adeel. I shipped ComicBase, a .NET MAUI app live on both the App Store and Google Play, so I know the app store review cycle and the discipline of keeping a cross platform codebase stable. For this I would start by profiling cold start with Firebase Performance and checking for unnecessary re-renders and heavy synchronous calls on the JS thread, then look at the native Swift and Kotlin modules for anything blocking the bridge. Happy to do the first fix free, around two hours, so you can see the profiling approach and communication before committing further. Are the slow transitions concentrated on a specific screen or spread across the app?

Hi, Your listing stacks React Native maintenance with backend and testing needs, yet without a clear app brief it is easy for a hire to waste cycles on the wrong stack or features. I will start from your existing React Native codebase, reproduce the maintenance issues, patch the root causes, and stabilize the backend endpoints the app depends on so releases stay testable. I can deliver within your $10 - 30 USD budget across clear milestones. Message me to get started. P.S. You listed both React Native and Flutter, so I will confirm which codebase is live before touching anything.

@codeandcommand

Performance issues on cross-platform apps usually trace back to unnecessary re-renders or bloated API calls draining the device. I would profile both the React Native or Flutter side and the backend first, then fix the worst offenders. I can start today and have a tuned build ready within 3 days. The budget and timeline here are starting points based on the post. Once I see the codebase, we can lock in real numbers. Want me to take a quick look now?

Hi, Your project doesn't need someone who simply follows the brief. It needs someone who understands what you're trying to achieve and figures out how to get you there. That's how I approach projects. Before writing code or jumping into execution, I want to understand the problem, the goal, and what success actually looks like for your business. I've spent the last several years turning business problems into working digital products, leading developers and designers, managing projects from idea to delivery, and delivering 40+ web and mobile projects. Do I know everything? Absolutely not. But I know how to solve problems. If I don't have the answer, I'll find it. I'll research, learn, test, ask the right questions, and keep working until we have a solution. And once I'm on board: It's our business. Our problem. Our responsibility. I'll give you my honest opinion, challenge ideas when I see a better approach, and never agree just for the sake of keeping things comfortable. I work with clients because I care about building things that succeed. If you're looking for someone who will take ownership rather than simply complete tasks, I'd be happy to learn more about what you're building.

@developper69

Hello, Your React Native app’s rising cold-start times and slow screen transitions call for targeted profiling rather than feature changes. I can work through the existing performance data, trace JavaScript and native bottlenecks, and apply focused improvements across the React Native, Swift, and Kotlin layers. I would compare Firebase Performance metrics with local profiling on mid-range devices, then validate memory usage, render behavior, startup work, and navigation timing. I’ll keep changes isolated in a branch, preserve the automated test suite, and submit a clear pull request with before-and-after measurements and maintenance recommendations. I’ll keep the optimization scope strictly limited to speed and responsiveness, with measurable validation for each change. Regards, Muhammad
