Kotlin jobs

I’m ready to bring my online store to Android and need a talented developer who can translate a straightforward e-commerce concept into a smooth, modern mobile experience. Because I’m starting with Android only, the build should be fully native (Java / Kotlin) or cross-platform so long as the Android release is polished and Play-Store-ready. Scope • End-to-end development of the Android app—from clean architecture and intuitive UI right through to final deployment. • Core e-commerce flow: product browsing, cart, checkout, and secure payment processing. (If you have proven plug-ins or gateway SDKs you prefer, let me know; I’m flexible as long as PCI-compliant options are in place.) • Admin-friendly integration so I can add or update inven...

...clean, modern look matters to me, so please wire in theme customization (at minimum light and dark, with room for future accents). I’m not asking for streaming, gesture navigation, or custom button layouts right now—those can stay on the wish-list until the core experience is rock-solid. I’m fine with ExoPlayer, Media3, or a comparable native library as long as you keep the codebase modular (Kotlin preferred, Java acceptable) and target the latest stable SDK. Smooth seeking, orientation changes that don’t restart playback, and hardware acceleration should work out of the box. Deliverables: • Full Android Studio project with clear, commented source code • Release-ready APK for quick testing on real devices (API 24+) • Short README...

My web application is already live, backed by Supabase and managed through a GitHub repository. The next milestone is a fully native mobile experience—Swift for iOS and Kotlin (or Java) for Android—mirroring the core web-app workflow without compromising performance or security.

...to launch a simple yet solid music-streaming application that runs natively on both Android and iOS. The core focus is a clean audio player that fetches and streams tracks from my back-end, with social-media login (Google, Facebook, or Apple) as the only authentication option—no email/password flow needed. I’m flexible on the tech stack: if you favour Flutter, React Native, Kotlin Multiplatform, or native Swift + Kotlin, that’s fine as long as the end result feels fast, modern, and stable on each platform. UI/UX assets, API endpoints, and sample tracks will be provided. Deliverables • Fully functioning Android and iOS apps compiled from a single codebase or two native projects • Social-media sign-in wired up and returning a valid user token ...

I want to turn “Wirna Mendrofa” into a polished mobile application and need a developer who can handle the full software-development cycle—from architecture and UI all the way to store submission. The finished product should run smoothly on both iOS and Android; how you reach that goal (native Swift / Kotlin, React Native, Flutter, or another framework) is up to you, so long as performance and maintainability stay top-tier. To be considered, send me a detailed project proposal. Walk me through your suggested tech stack, development milestones, testing process, and maintenance plan, and include links to any similar apps you’ve built so I can see your past work in action. Clear, well-commented code in Git, regular testable builds, and comprehensive deployment...

...can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: • A brief outline of how you prefer to structure an Android project • Any simil...

...clips remain in the local Room/SQLite store indefinitely, while every unpinned clip should be purged exactly one hour after its creation time. I’m fine with the standard Android UI conventions—think long-press selection, a pin icon in the contextual action bar, and a small pinned indicator inside each row. No custom assets are required beyond the built-in Material icons. The current codebase is Kotlin, minSdk 24, using ViewModel + LiveData. Please stay within that stack. If you see a cleaner Jetpack-recommended way to schedule the one-hour expiry (WorkManager or AlarmManager), let me know and implement it. Deliverables • Updated source code with the pinning logic and expiry scheduler • Any new database entities or migrations applied • Brief mar...

...in-app behaviour. I’m open to the exact technique you use (TensorFlow Lite, ML Kit, embedded models, or a lightweight cloud call), so long as it stays responsive on typical mid-range Android devices. No third-party property-management or CRM integrations are required; the app should run as a self-contained product with its own lightweight backend or local data layer. A clean Material-style UI, Kotlin codebase, and modern Android architecture (Jetpack components, MVVM or similar) will make maintenance easier down the road. Deliverables • Full Android source code and build instructions • Compiled, installable APK targeting Android 11+ • README that documents model choice, training data source (if custom), and how to retrain/replace it • Short vid...

...production build of my app is intermittently crashing, and I need a clean, targeted code update to eliminate these functionality-related bugs without introducing new issues. The crashes appear after recent OS updates and seem tied to memory handling inside two core screens; logs point to null pointer exceptions in the data-binding layer. You’ll receive: • Full Git repository access (Android, Kotlin + a small legacy Java module) • Current crash logs from Firebase Crashlytics and Logcat • A short video that reproduces the issue on two devices What I need from you: 1. Diagnose the root cause of the crashes. 2. Refactor or patch the affected classes so the app runs reliably across Android 8-14. 3. Commit code in a separate branch with clear comm...

I need a straightforward yet polished online-shopping app for my supermarket, available on both iOS and Android. The primary goal is letting customers browse products and place orders from their phones; everything else is secondary to a smooth buying experience. Because I’m not on a tight deadline, you’ll have the freedom to choose the tech stack—native Swift/Kotlin or a cross-platform approach such as Flutter or React Native—so long as the final result feels fast and intuitive. Key deliverables I’d like handed over: • Shopper-facing app for iOS and Android, ready for App Store and Google Play submission • Clean, well-documented source code • Simple admin or API hook that lets me update products, prices, and stock in real time &...

...episodes and tracks balance in real-time. • Smooth audio streaming with background play; buffering and bitrate handling should feel invisible to the listener. (Offline downloads are optional for a later sprint, so build with that future toggle in mind.) Design & tech notes The UX should echo popular audio apps—clean mini-player, intuitive queue, dark/light mode if practical. I am comfortable with Kotlin or modern Java and would like well-structured, maintainable code. If you rely on a backend (Firebase, custom REST, etc.) outline the stack and provide clear API documentation so future content ingestion is straightforward. Deliverables 1. Source code and compiled APK ready for Play Store submission. 2. Admin-side setup instructions for managing stories, pricing ti...

...feature is rock-solid time tracking: staff must be able to clock-in, clock-out, record breaks, and review their own daily totals from any modern iOS or Android device. Shift planning and push notifications are not required in this phase, but the architecture should leave room for those additions later. For this initial release, please deliver: • A clean, intuitive mobile interface (native Swift/Kotlin or a cross-platform stack such as Flutter or React Native is fine) • Secure user authentication tied to our existing employee IDs • Real-time clock-in/out with local offline support and automatic sync once connectivity returns • A lightweight back-end (Firebase, Supabase, or a simple REST API with PostgreSQL) storing punch data and producing daily time s...

I need a skilled Flutter developer to plug a very specific feature set into my...recording when my code tells you to, and send the resulting MP4 to the backend with the required headers and auth token. No UI beyond a minimal overlay is expected, so you can concentrate on the functionality itself. Deliverables • Flutter module(s) that expose AR filters, advanced eye tracking, video capture, and an async upload call • Clean, well-commented Dart code plus any native Swift/Kotlin snippets wrapped with platform channels if needed • Quick README explaining integration points and outlines for build settings on both platforms I already handle all server-side processing; I just need this mobile piece integrated and tested on one recent ARCore phone and one ARKit devi...

...Users must be able to discover new people, send and accept requests, organise their contacts, and browse basic profiles in a fluid, Material-design interface. Messaging and photo sharing are out of scope for now; the architecture, however, should keep future modules in mind. You’ll receive my wireframes and brand assets on day one. From there I need a clean Android Studio project, preferably in Kotlin, targeting API 26+. Please follow standard MVVM patterns, use Jetpack components where they add value, and keep third-party libraries lightweight and well-documented. Deliverables • Complete, well-commented source code and project files • Signed release-ready APK/AAB plus debug build • One-page setup & deployment guide Acceptance criteria The ap...

The issues are isolated to the UI layer: the now-playing fragment, its data-loading helper, and the activity that hosts them. I can point you straight to the offending methods, but I need a clean, compile-ready project and a brief note on what you changed so I can learn from the fix. You’ll be working with: • Android Studio (latest stable) • Java source only – no Kotlin in this module Acceptance: the project builds without warnings, launches, and the UI loads station data and switches fragments without throwing exceptions on at least API 23+. If you’re comfortable speaking Tamil so we can walk hrough any remaining doubts o...

I need a reliable Android developer to jump into my existing project and resolve a few lingering bugs. The code-base is stable overall, but a handful of issues are affecting the user experience and I’d like them cleaned up quickly so I can push the next release to Google Play. You will receive: • The current Android Studio project (Kotlin) • A concise list of the reproducible bugs with steps, expected vs. actual behaviour, and device logs where available I expect: • Clean, well-commented fixes that slot neatly into the existing architecture • No regressions elsewhere in the app—please test on at least two API levels • A pull request or zipped project, plus a signed APK so I can verify on real devices If this sounds straightforw...

Technical notes • Android-native (Kotlin preferred, Java acceptable) in Android Studio. • Clean MVVM architecture, material-3 UI, dark/light modes. • Room or lightweight Firebase for local persistence; open to your suggestion. • Code must be well commented—the matrix calculation is unique, so clarity is critical. Deliverables 1. Source code in a private G...

I am ready to turn a concept into a fully-functional Android application and need a developer who can guide the project from initial design through Play-Store-ready build. The scope is limited to Android only—no iOS version is planned—so I want the solution to take full advantage of the Android ecosystem and its latest SDKs. Key things I will look for are clean, maintainable Kotlin or Java code, a modern UI that follows Material guidelines, and a robust architecture that scales if we later add new modules. I will share wireframes and a concise feature list as soon as we agree on the collaboration, but you can expect standard app elements such as user onboarding, data storage (local or cloud, depending on your recommendation), and basic analytics. Deliverables I expect:...
