I’m updating an existing Android application and need a developer who can tackle two things at once: refresh the UI and eliminate the bugs users keep running into. On the design side, I want the screens to look cleaner, feel more modern, and guide users intuitively through every flow. On the engineering side, the current build suffers from glitches across the interface, functional misfires in a few core features, and noticeable slow-downs on lower-end devices. Here’s what success looks like to me: • Revamped layouts that follow material-design best practices and scale gracefully on phones and tablets • Smooth, crash-free navigation with all buttons, menus, and gestures responding instantly • Functional fixes confirmed by passing our existing Espresso/UI tests (I’ll provide them) • Performance improvements demonstrated through reduced launch times and scrolling FPS gains in Profile and Feed screens You’ll have direct access to the Git repo, existing XML/Jetpack Compose files, and crash logs from Firebase. Once you’ve pushed stable changes, I’ll test on multiple devices before giving the final green light. If you’re comfortable refining UI while squashing interface, functionality, and performance issues in one sprint, I’d love to see how you can help.

I can handle both the UI refresh and the stability/performance fixes in a single focused sprint while keeping your existing architecture intact. My approach will be a mix of design refinement and deep debugging so the app not only looks modern but also runs reliably across devices, including lower end Android phones. What I will work on: 1. UI modernization using Material Design best practices 2. Layout cleanup for XML and Jetpack Compose screens 3. Fixing interface glitches and broken user flows 4. Resolving functional bugs using crash logs and test feedback 5. Performance optimization for slow screens (Profile and Feed) 6. Improving launch time and scroll smoothness (FPS stability) 7. Ensuring all Espresso and UI tests pass after changes How I will validate quality: 1. Run and fix issues using Firebase crash logs 2. Verify all navigation and interactions are responsive 3. Compare performance before and after optimizations 4. Ensure test suite stability with no regressions I have experience working on Android apps where UI overhaul and performance tuning had to happen together without breaking production logic, especially in mixed XML and Jetpack Compose codebases.

I understand that your Android application is facing significant challenges with both user interface design and performance issues, which can hinder the overall user experience. With my 12+ years of experience in mobile development, including expertise in Flutter and Kotlin, I can provide a comprehensive solution tailored to your needs. I will focus on implementing material-design principles to create modern layouts that not only look appealing but are also intuitive for users. Addressing the bugs affecting functionality is equally critical; I'll utilize tools like Firebase for crash log analysis and ensure that all fixes are validated through Espresso/UI tests. Moreover, optimizing performance through reduced load times and improved scrolling responsiveness will be a key priority, especially for users on lower-end devices. Could you share more details about the specific core features suffering from glitches? This will help me tailor my approach effectively.

Hi, Your app needs two things done properly in the same sprint: a cleaner modern Android UI and deep stability/performance fixes across existing features. I work on scalable mobile systems with strong focus on UI performance, architecture, and production stability. I’m comfortable working directly with existing Android codebases, Firebase crash logs, XML/Compose screens, and test-driven fixes. Most of my recent work involves optimizing mobile experiences, improving rendering performance, fixing navigation inconsistencies, and making apps feel significantly smoother on lower-end devices. My approach would be to first isolate the crashes and slow UI layers, then refactor the affected screens using cleaner Material Design patterns while optimizing launch speed, scrolling performance, and interaction responsiveness. All fixes will be validated against your existing Espresso/UI tests before delivery. One quick question: are the biggest FPS drops currently coming from Feed rendering, API/state handling, or image loading/cache behavior? Best regards
