@mundhava

As an experienced mobile app developer, specifically proficient and skilled in Flutter/Dart, I have a thorough understanding of platform-specific quirks, package integrations, and the entire release workflow. Over the past 8 years, I've successfully taken on projects much like yours and guided them through to store approval. With each app, I demonstrate profound investigative abilities to identify UI/UX and performance issues that may arise on different devices - both Android and iOS, thereby resolving them cleanly. My goal has always been to provide excellent quality, and this reflects directly in clean-well commented codes/documentations that meet industry standards. My deep knowledge extends to profiling apps for performance optimization as well as managing all stages leading up to secure releases for Android and iOS platforms as required by your project. Your satisfaction is my priority; I offer not just good service but also a commitment to delivering happy results. I am personally motivated to bring your app from being bug-ridden to an optimal state enhanced for robust navigation, speed, and consistency. With my experience with RESTful services, geolocation services among others integrated into your app should be of no hassle.

@mutahrar

Hello, I hope you are doing well. Your goal of stabilizing your Flutter app and successfully publishing it on both app stores immediately caught my attention. Project Scope: I understand your app is already feature-complete, but currently affected by UI/UX inconsistencies, performance issues, and release readiness gaps on both Android and iOS. The main objective is to cleanly fix these issues, optimize performance, and ensure a smooth, production-ready release to Google Play and the App Store. Solution: I can thoroughly audit your existing Flutter codebase to identify and fix UI glitches, layout issues, navigation inconsistencies, and performance bottlenecks such as rebuild inefficiencies, laggy scrolling, or memory leaks. I will profile the app, optimize rendering performance, and ensure smooth cross-device behavior on both Android and iOS. Once stable, I will handle full release preparation including signing configuration, build generation (AAB/APK and IPA), and submission support for both stores to ensure approval readiness. I have experience debugging complex Flutter applications, improving performance of production apps, and managing full deployment workflows to both Google Play and the App Store. Looking forward to your response.

@Rupal878

Hello, your project is exactly the kind of rescue-and-release task where experience matters most. Since the app is already feature-complete, the real priority now is refining quality, stability, speed, and ensuring both stores approve the release smoothly. I can step into the existing Flutter codebase, diagnose UI/UX inconsistencies, fix navigation and layout issues, optimize performance, and take the app through final deployment on both Google Play and Apple App Store. My approach focuses on clean debugging, profiler-based optimization, device testing, memory/performance tuning, and production-ready builds with proper signing, certificates, and submission compliance. The goal is not temporary fixes, but a polished app ready for public users. To assess the workload accurately: Is the app currently using the latest stable Flutter version or an older setup? Are the major issues more related to UI bugs, crashes, or slow performance? Do you already have active Play Store and App Store developer accounts ready?

@alluankit01

Hi, I can fix the UI/UX and performance issues in your Flutter app and prepare it for release on both Google Play and the App Store. I’ll first review the existing Flutter/Dart codebase, reproduce the visual glitches, navigation issues, slow screens, and performance problems, then fix them cleanly without breaking completed features. I’ll also check common release blockers like app permissions, signing, package versions, build errors, iOS provisioning, Android AAB setup, and store metadata. My focus will be making the app feel stable and smooth: faster launch, clean layouts on Android/iPhone, better scrolling, no obvious memory leaks, and store-ready builds. After the fixes, I’ll provide the updated code, AAB/APK, IPA guidance, changelog, and release notes, then support the submission process until both stores are ready for public listing. Best regards Ankit

@utsav007pandya

Greetings, I am a Flutter developer and mobile performance specialist. I'll audit your existing Flutter codebase, fix UI/UX inconsistencies across Android and iOS, and resolve layout, navigation, and rendering issues to ensure a smooth and consistent user experience. I'll also profile the app to eliminate performance bottlenecks, memory leaks, and slow transitions so it runs efficiently on both platforms. Once stabilized, I'll handle full release preparation including Android (AAB/APK) and iOS (IPA) builds, signing setup, provisioning profiles, and store submission support to ensure successful approval on Google Play and the App Store. You'll also receive clean, well-documented code and a concise release changelog. Do you already have developer accounts set up for both stores, or should I assist with that setup as well? Better we do a quick chat to ensure few things about the task. Ping me when you're available.

@OBRY8246

Hi, I can help stabilize your Flutter app and take it all the way through to successful store release. I’ve worked on similar cases where apps were feature-complete but needed focused debugging, UI refinement, and performance optimization before going live. I’ll start by identifying and fixing UI/UX issues across devices, ensuring layouts and navigation behave consistently on both Android and iOS. In parallel, I’ll profile the app to address performance bottlenecks—improving load times, smoothness, and overall stability. Once everything is solid, I’ll handle the production build process, including signing, provisioning, and submission to both Google Play and the App Store, making sure it meets their review requirements. You’ll receive clean, maintainable code, tested release builds, and clear notes so you understand what was fixed and how to manage future updates. I’m ready to review your codebase and get started. Best regards

@mihajlodjokic

Let me get it done, I'll systematically audit your Flutter codebase to identify performance bottlenecks and UI inconsistencies, ensuring a polished, high-performance experience on both Android and iOS before managing your full store submission process. Your project will be finished in 2-3 weeks, I have done similar stuff before. Here is how I would approach it: 1. I can do a free demo if needed. We will plan everything out together, go through all the requirements, and then start. 2. Perform a deep profiling session using Flutter DevTools to identify memory leaks and frame drops. 3. Refactor UI components and layout widgets to resolve platform-specific rendering glitches and navigation issues. 4. Optimize app assets, state management, and build configurations to improve load times and responsiveness. 5. Handle all production signing, provisioning profiles, and store metadata to ensure a smooth, successful approval process on both stores. Let's talk as soon as possible and get it done. Best Regards, Mihajlo
