    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.

Key features my prototype covers and that I need fully implemented are: • Order tracking from placement through fulfilment • Menu management that vendors can update in-app • Automatic customer notifications on status changes • A dedicated vendors dashboard for viewing live orders and basic analytics * user c...

    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.

    I want a sleek, web-based text chat application built with React on the front end, Node.js on the back end, and Firebase handling real-time messaging as well as user authentication. The interface must load quickly and feel at home both on desktop browsers and on mobile screens, so responsive layout and touch-friendly controls are essential. Core experience • Real-time text conversations that update instantly, complete with emoji and sticker support. • Group rooms for up to 20 participants, each showing typing status and read receipts. • Simple email-and-password sign-up, profile page, and photo upload. • One-to-one and group image sharing (no videos or docs for now). Look & feel Think Telegram or Signal stripped to the essentials: soft neutral backgrou...

    FlutterFlow MVP Mobile App Build

    Verificado

    I’m turning the first version of my mobile product into reality and need one dependable developer to own the build and guide the technical choices along the way. We’ll work in FlutterFlow or Bubble—whichever you believe will get us to market fastest—on top of a Firebase backend. I’ll handle product direction; you’ll handle code and architecture. Clean functionality is the goal, not pixel-perfect polish. The MVP must launch with: • User profiles (avatar, basic settings) • Real-time messaging between users • A content-sharing area (text, images, short video) The UI style should feel modern and colourful while remaining intuitive. I’m aiming for a working build as soon as possible, so I expect a short progress demo or Loom walkt...

    The task is to turn my early-stage concept into a working hybrid MVP that will launch first on the web. Everything else in the product can stay bare-bones for now—the priority is a clean, secure user-authentication flow that covers sign-up, login, password reset and session handling. Social or single-sign-on options (Google, Apple, etc.) would be great if they slot in easily. I have user stories and low-fidelity wireframes ready. Choose any modern stack you’re comfortable with—React or Vue on the front end, Node/Express, Django or a similar REST backend, paired with JWT or OAuth for token handling. What matters is that the codebase remains portable so I can wrap it later with Capacitor, Ionic or another bridge for iOS and Android. Deliverables • Deployable web bu...

    I’m building a single platform that works both as an information hub and a true instant-booking engine for ground-transport services. Visitors should be able to land on the site, read about our fleet and policies, get a live quote, and confirm a ride immediately—no approval queue, no waiting. Key flows • Instant booking only. A real-time price and availability check fires the moment a customer clicks “Book now,” then records the reservation on our side and with our partners via XML. • XML integrations with Elife, Mozio, and TransferZ are mandatory. The site must push new bookings, pull updates, and keep status changes (assigned, picked-up, completed) fully in sync. • Account roles are limited to Admin and Drivers. Customers book as guests;...

    I need a lightweight, real-time chat application that runs in the browser. The focus is purely text messaging, but users must be able to insert and render emojis naturally inside each message. The core flow I’m picturing is simple: a visitor lands on the page, chooses a display name, and immediately joins a public chat room where messages appear instantly without refreshing the page. WebSocket (or a similar push technology) will be necessary to keep the conversation live. Clean, responsive UI built with vanilla JS, React, Vue, or another modern front-end framework is fine as long as it loads fast and looks good on both desktop and mobile browsers. Key points I will review during hand-off: • Messages and emojis show up in real time for every connected user. • Frien...

    I’m planning 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 toke...

    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 notes ...
