Hi! I’ve worked on Kotlin/Java Android apps where the goal was exactly this—tight performance refactors, Material UI refreshes across API 26–34, and fixing Crashlytics issues without disturbing live users. I’m comfortable diving into existing codebases, optimizing battery/memory use, and adding small features like onboarding, notifications, and settings toggles in a clean, version-controlled way. With Jira tasks and repo access, I can move quickly and keep changes well documented for easy review. Looking forward for your positive response in the chatbox. Best Regards, Arbaz H

✋ Hi there. I can upgrade your existing Android app with focused performance fixes, UI polish, and small feature additions while keeping the current users unaffected. ✔️ I have solid experience working on live Android apps using Kotlin and Java, refactoring code, improving battery usage, and updating UI with modern Material components. In a previous project, I optimized an app already on Google Play, fixed Crashlytics issues, added onboarding and notification features, and shipped a clean update without regressions. ✔️ For your project, I will review the codebase, target slow paths, and refresh screens to stay compatible from Android 8 through Android 14. I will implement the queued features based on your specs, follow Jetpack best practices, and keep changes organized in clear commits. ✔️ I will resolve reported crashes, validate fixes with a QA build, and deliver a pull request with a short changelog explaining each change. Feedback cycles will be quick and clear. Let’s chat to review the repo and start the sprint. Best regards, Mykhaylo

I’ve worked with healthcare and fintech apps where performance and UI polish directly impacted user retention. In similar projects, refactoring Kotlin code to reduce battery drain and improve load times brought measurable gains. I’ll start by profiling slowdowns and optimizing key code paths without disrupting the current user experience. Upgrading UI with Material Design components from Android 8 through 14 is straightforward, and I can ensure consistent behavior across versions. For the small features like in-app notifications and onboarding, I’ll break the implementation into clear steps and confirm details as you share specs. I’m familiar with Firebase Crashlytics workflows and can prioritize crash fixes efficiently. After completing changes, I’ll provide a clean, version-controlled PR plus a concise changelog, making it easy for you to review and track improvements. Quick question: Are there any existing CI/CD pipelines for builds and Play Store deployments, or should I factor setup into the sprint? Ready to dive in and elevate your app’s performance and user experience.

@angelantonioc

Hi, I’ve reviewed your Android upgrade goals and I’m ready to help sharpen performance, update UI with modern Material components, and land those small features without destabilizing current users. I’ve built and shipped multiple Android apps, with focus on battery life and smooth UIs. I’ll approach this by targeting hot paths in Kotlin/Java, profile and refactor, and ensure compatibility from Android 8 to 14. How I’d implement it: - Audit and refactor key screens and background work to reduce slowdowns and battery drain - Refresh screens with updated Material Design components across API levels - Add 2-3 small features (in-app notifications, onboarding, settings toggle) using your specs - Reproduce and fix Firebase Crashlytics crashes; deliver a QA build - Produce a clean PR with a concise changelog Availability: I can start now; expect a first QA build within 3–4 days, depending on access to Jira/tasks. Would you like the new features rolled out in a staged manner or all at once in the first QA build? Thanks,

@maksymh31

Hello, I’ve read your brief and can refine performance, modernize the UI, and add lightweight features without disrupting current users. Approach: run profiling and static analysis to locate CPU/battery hotspots, refactor Kotlin/Java hotspots and adopt Jetpack patterns; update screens to Material components with compatibility from Android 8 (API 26) through Android 14 (API 34); implement 2–3 small features from your specs (in-app notifications, lightweight onboarding, settings toggle); fix reproducible Crashlytics issues and deliver a QA build. I will produce a version-controlled PR with a clear changelog and staged commits for your quick review. How I’ll start and what I need: grant repo access, Jira task list, design assets, and the detailed specs for the queued features; I’ll run an initial smoke profile and push a diagnostic branch within 24–48 hours. I recommend a focused 7-day sprint to deliver the above and iterate on feedback. Which queued feature should I prioritize first, and can you provide the detailed spec and any acceptance criteria for that feature? Best regards,

@GobindSawarn

I'm an Android specialist with 5+ years of experience taking live apps to the next level — exactly the kind of refinement project you're describing. I've done multiple "polish & performance" sprints on production Kotlin apps: Refactored slow screens (RecyclerView, Room queries, heavy coroutines → 40-60% faster load & lower battery drain) Migrated legacy XML layouts to modern Compose / Material 3 components (Android 8–14 full support) Added lightweight onboarding, in-app notifications (Firebase Messaging), settings toggles, and fixed dozens of Crashlytics crashes Delivered clean PRs with meaningful commit messages, detailed changelogs, and tested release builds My usual flow for such projects: Quick repo audit + Crashlytics deep-dive (1–2 days) Performance profiling & targeted refactors (Jetpack Profiler, baseline profiles, Paging 3, etc.) UI refresh with Material You / dynamic colors where it makes sense Implement your 2–3 queued features from specs Full QA pass (emulators + real devices 8.0–14), crash verification PR + changelog + updated APK for your review I work cleanly in Android Studio with Jetpack (Compose/View, Hilt, Navigation, DataStore, etc.) and I'm very comfortable with private repos + Jira. Happy to review the repo, discuss your queued features, and suggest a few quick wins once I see the code. Let's hop on chat or a quick call to align on priorities and timeline — excited to help make your app noticeably smoother and more delightful!
