If you prefer Kotlin, Java, or Flutter, please indicate why your choice will give the best performance and maintenance path. The ideal turnaround is within a week. Let me know the toolchain you expect to use, any similar projects you've completed, and a...

The goal is to release a polished mobile application for both iOS and Android within the next four weeks. All core features, UI assets, and store-ready builds must be delivered on that timeline, so I need a tightly coordinated team that can handle design, development, QA, and deployment in parallel. I’m open to a native Swift + Kotlin approach or a shared-code framework such as Flutter or React Native—as long as performance and store compliance are guaranteed. You’ll receive a concise feature brief on kick-off, daily access to Figma wireframes, and API documentation from my backend developer. Expect quick turnarounds on feedback; I’m committed to unblocking you fast so the schedule stays intact. Key deliverables • Two production-ready apps submitted to...

...app should mirror the key functions of the site while giving users a smooth, mobile-first experience—quick onboarding, push notifications, and effortless ways to track their earnings on the go. I will provide wireframes and the main user flow once we start; I’m open to your suggestions on tech stacks as long as they suit both a modern web front end and a stable Android build (React, Flutter, Kotlin, or similar—your expertise matters here). Deliverables I expect: 1. Responsive website ready for production hosting. 2. Fully tested Android APK plus source code. 3. Simple admin panel (shared or separate) so I can monitor users, payouts, and content. 4. Clear deployment notes so I can replicate the setup or hand it off to future developers without heada...

I need a developer who can take an Android-only concept and lui it into a working mobile application. You and I will start by refining the functional requirements, then move through UI implementation, back-end or API hookups (if they prove necessary), rigorous device testing and finally packaging the build for Google Play release. Kotlin or modern Java inside Android Studio is preferred so the project stays future-proof. Clean, well-commented code checked into Git is a must, along with a short hand-off document so I can keep maintaining the project once it’s live. Deliverables • Source code in a Git repository • Signed APK/AAB ready for Play Console upload • Brief setup & maintenance guide Acceptance criteria • App installs and runs smoothly o...

...natively on both Android and iOS. Devices should discover one another automatically, relay files even when they are not in direct range, and keep transfers alive as phones move through the topology. No internet connection, central server, or cellular data may be required at any point; every packet must flow peer-to-peer until it reaches its destination. Core scope • Build separate native clients (Kotlin/Java for Android, Swift/SwiftUI for iOS) or use a cross-platform framework if it can still leverage each OS’s low-level mesh APIs (Wi-Fi Aware, Wi-Fi Direct, Bluetooth LE, Multipeer Connectivity, etc.). • Implement routing that supports at least three hops in practical tests, automatically re-routing around dropped nodes. • Transfer any standard file ty...

...cleanly abstracted so we can swap providers later if needed. 4. As soon as payment clears, the request status needs to update automatically in the admin panel and reflect in the user’s history screen. 5. admin can upload a pdf file to the request sent as receipt completing the request. 6. admin would have multiple user on his side to manage/assign request. Core deliverables • Android client (Kotlin or Java) with profile management, vehicle CRUD (restricted edit), tax-request flow, and payment integration • Simple, secure admin web panel (framework of your choice) that lists, filters, and changes request states • RESTful backend or Firebase setup to sync data between app and admin panel • Documentation for build, deployment, and environment va...

...create a full-featured social-networking application dedicated to Android. The core idea is to let users connect, share updates, and interact in real time on a modern, intuitive interface that feels familiar yet fresh. I already have the concept and key user journeys drafted; what’s needed now is end-to-end Android development—from setting up the architecture through to a Play Store–ready build. Kotlin (or clean Java) and a reliable backend service such as Firebase, Supabase, or a custom REST API will suit the stack. Attention to smooth onboarding, secure authentication, push notifications, and an easily browsable feed is essential. Thoughtful UI/UX design that follows current Material guidelines will help the app feel polished from the first launch. Deliverab...

I need a full-stack developer to build the first release of my social media application for Android. The goal is to ship a clean, production-ready APK that lets users create profiles, exchange direct messages, and scroll through a dynamic content feed where both photos and videos can be uploaded and viewed. The scope covers everything from UI/UX and native Android development (Kotlin or Java) to the backend APIs, real-time messaging layer, media storage, and basic moderation tools. While the initial launch is Android-only, I’d like the architecture to be modular enough that we can add iOS or a web client later without rewriting core services. Key deliverables • Fully functional Android app with:  – Secure user sign-up / login (email, phone, or social) &...

...on-device. Once created, the code should be shareable through the native Android share sheet (email, WhatsApp, Bluetooth, etc.) and scannable from within the same app so staff can verify the embedded information without leaving the interface. No need to store codes locally; the focus is on quick generation, instant scan confirmation, and easy sharing. Core requirements • Android-native app written in Kotlin or Java • Input screen to capture/choose a photo and enter the accompanying text message • Real-time QR code generation from that combined payload • Built-in scanner using the device camera (ZXing, ML Kit, or similar) • One-tap share button for the generated QR image Deliverables 1. Production-ready APK for testing on Android 9+ devices ...

...and recurring or one-off expenses. • The app groups those entries into customisable categories and shows what’s left in real time. • Clear visual cues—charts, progress bars or colour highlights—alert users when they are about to exceed a category or overall limit. • All data must be stored securely on-device with the option to export or back up to Google Drive. I’m happy for you to pick Kotlin or Java, but the final build must run smoothly on recent Android versions and pass Play Store requirements. Clean, well-commented source code and an installable APK are mandatory hand-offs; a concise setup/read-me will help me test rapidly. Let me know which libraries or frameworks you plan to use for UI, database and charting, plus any suggest...

Our next mobile release is on hold until five high-priority bugs are resolved on both Android (Java/Kotlin) and iOS (Swift). I need someone who can jump into the codebase right away, trace the problem areas independently, and ship production-ready fixes. Scope You’ll work on both platforms simultaneously; the most critical symptom on iOS is a crash that slips past TestFlight. Source access is already prepared, and while documentation is spotty I’m available for quick video calls whenever clarification is needed. You’ll also have a direct Slack line to our backend engineer for anything API-related. Deliverables • Diagnose the root cause of each of the five reported issues on Android and iOS • Commit clean, well-commented patches that compile without wa...

I need a skilled mobile developer to create a full-featured social networking application for Android. The core idea is to let users connect, share posts, comment, and follow each other in a clean, modern interface that feels as smooth as the leading social platforms. I’m already clear on the platform—Android only—so you can focus your efforts on native Android Studio tooling, Kotlin or Java (your choice), and proven libraries for authentication, push notifications, image/video handling, and real-time updates. A lightweight, well-documented back-end architecture (Firebase or any RESTful solution you prefer) is welcome as long as it scales easily. Key deliverables: • Production-ready APK and Play Store-ready bundle • Complete, readable source code wi...

...phone, or social logins; I’m open to Firebase Auth, AWS Cognito, or another secure alternative you prefer. For storage and streaming, feel free to propose the stack—S3 + CloudFront, Firebase Storage, or something comparable—so long as uploads encode quickly and playback is smooth on slower connections. Deliverables • Universal iOS & Android app built with React Native, Flutter, or native Swift/Kotlin—whichever gets us to market fastest without sacrificing performance. • Admin dashboard (web) for content moderation, user reports, and basic analytics. • Clean, well-commented source code in Git, plus deployment scripts/instructions for the stores and backend. • Post-launch support window to fix any critical bugs that appear in the fir...

Please use whichever stack you’re most comfortable with—React Native, Flutter, Swift/ Kotlin, or another proven option—as long as the chat functionality stays smooth and maintainable. I’ll supply basic branding assets and can handle App Store accounts; you’ll focus on architecture, coding, and deploying a test build we can iterate on together. If you’ve shipped chat-centric apps before, especially ones that scale grace...

...messages, lets me craft quick text replies, and sends them out with a single tap. Core flow is plain text messaging; voice, video, or heavy media handling isn’t required. Push notifications matter: every new incoming chat must trigger a heads-up notification that deep-links straight into the reply screen, so I can answer without hunting through layers of the app. You’re free to build in Java or Kotlin—whichever you work faster with—so long as the code compiles cleanly in Android Studio and targets recent versions of the Android SDK. Deliverables • Full Android Studio project with well-commented source • Signed or unsigned APK for quick testing • Brief read-me explaining setup, permissions needed, and how the notification-to-repl...

Our production app is written natively—Java/Kotlin on Android, Swift on iOS—and five high-priority bugs are blocking the next release. I can give you full source access; documentation exists, but only partially, so you’ll need to be comfortable tracing code paths on your own. I’m ready to jump on video calls whenever you need context or quick feedback, and you’ll also have a direct line to the backend engineer for anything server-side. What I need from you • Identify the root cause of each reported issue on both platforms • Deliver clean, well-commented fixes that compile without warnings • Verify performance isn’t degraded and no new regressions appear • Push code to our repo and walk me through the changes on a brie...

I already have a fully functional HTML/JavaScript baccarat predictor; the logic is proven and stable. What I need now is a production-ready package that runs smoothly everywhere. My top priority is seeing the Android and iOS versions live, and I also want a polished web app released in parallel. I’m open to whatever approach you believe will deliver the best performance—native Kotlin/Swift, Flutter, React Native, or another cross-platform framework—so long as the end result feels fast, looks modern, and never crashes. You’ll begin by reviewing my existing codebase, extracting the prediction module and UI assets, then adapting them to the chosen stack. A clean, minimal interface is a must, and I’m happy to collaborate on final styling details. Once the ...

...native Android (Kotlin / Java) to finish the last stretch of our mobile app. The core build is already in Flutter, but several screens need a fresh look that still feels unmistakably on brand. Some layouts only need slight tweaks, while a handful will benefit from a full visual overhaul—your guidance on keeping typography, colour, and iconography consistent is key. Beyond the UI work, I’d like to introduce a Snapchat-style experience. In our case that means native, camera-driven interactions with on-device verification plus the ability for users to delete captured photos and videos at any time. If you bring ideas from Stories, Filters, or similar mechanics, we can discuss them, yet the must-have is that streamlined capture / review / delete flow built directly in Swi...

I need a dedicated Android app that lets customers browse, add to cart, and securely check out with my products—all within a clean, modern interface. Because the primary goal is e-commerce, performance and payment security matter as much as the look and feel. I’m focused solely on Android for this first release, so please bring your preferred stack—whether it’s Kotlin with Jetpack, React Native, Flutter, or another approach—and explain why it fits the job. Alongside the APK, I’ll need any supporting back-end services set up so orders flow straight into my dashboard. To keep us aligned, outline: • your proposed architecture and key libraries • the payment gateway and authentication workflow you recommend • milestone breakdown f...

...While the core concept is clear—an Android app that handles time with absolute reliability—I’m still flexible on the exact feature set. I’m leaning toward classic timing tools such as reminders, countdowns, or running stopwatches, but I’d value your input on what delivers the best user experience and technical performance. Here’s what I expect: • A clean, responsive Android interface built in Kotlin or Java that showcases millisecond-level precision. • Robust timing logic that remains accurate when the app is in the background or the device is under load. • Well-structured, maintainable code with concise documentation so future iterations are straightforward. If you have experience building timers, schedulers, or any real-time ...

Nice to have but not required: social login, in-app messaging, or multi-currency support—flag if you can tackle any of these. I prefer someone with at least 1–3 years of proven mobile development, fluent in Kotlin/Java and Swift/SwiftUI (or React Native/Flutter if you can guarantee native-level performance). Clear communication and reliable sprint delivery are non-negotiable. Send over a concise proposal highlighting similar travel or real-time data apps you’ve shipped, the tech stack you’d pick, and an estimated timeline for an MVP upgrade plus iOS parity. Looking fo...

I am ready to turn my idea, “Padil 8 Rupiah,” into a fully functioning Android application and I need an experienced mobile developer to guide it from concept to Google Play upload. The core product will run exclusively on Android, so you should be comfortable working in Kotlin or Java with Android Studio, following current Material Design guidelines and the latest SDK best practices. Starting with a brief discovery session, you will help refine core features, map the user flow, and set a realistic timeline. From there, I expect clean, well-commented code, responsive layouts that adapt to various screen sizes, and seamless performance on recent Android versions. Deliverables: • Complete Android Studio project with source code • Signed, installable APK...
