I’m looking for a full-stack mobile developer who can turn my existing study materials into an AI-powered practice app for both Android and iOS. I already have everything the engine needs—past exam papers from 2018-2025, a full question-and-answer book (with explanations), and an additional reference text. Your job is to design and build the app and connect an AI layer that reformats each multiple-choice question and attaches a clear, step-by-step explanation to the chosen answer and to have an ai agent that keep updating everything in the app Core flow • Users create an account or sign in with a simple email-and-password screen. • Once inside, they can browse or search the question bank, attempt multiple-choice items, submit their answer, and immediately receive an AI-generated explanation. • Content comes from my three sources; the AI agent only needs to rephrase, tidy formatting, and expand on the explanation—it does not have to invent new questions at this stage. • The same codebase should ship to Android and iOS (React Native, Flutter or similar is fine). Key deliverables 1. Mobile app source code and working builds for Android & iOS. 2. Admin interface or script that lets me upload new questions in bulk. 3. Server-side logic / cloud functions that invoke the AI model, reformat the question text and attach the expanded explanation before serving it to the user. 4. Basic analytics (number of questions attempted, accuracy rate) stored securely. 5. Documentation covering deployment, API keys and how to swap the AI provider if needed. Acceptance criteria • Smooth email/password sign-up and login. • All multiple-choice questions render correctly on both platforms. • AI response time below three seconds for explanations on a mid-tier device. • Code passes a hand-off review and builds without errors on my machine. If you have shipped cross-platform apps before and are comfortable weaving in an AI completion endpoint (OpenAI, Claude, PaLM, etc.), let’s talk timelines and your recommended architecture. My budget is 350 usd Thanks

Hi, Your project is very clear and well-structured—I’d be happy to help you turn your study materials into a scalable AI-powered practice app. I have experience building cross-platform mobile apps using Flutter/React Native with backend integrations and AI APIs. Based on your requirements, I’d recommend a clean architecture using a single mobile codebase, a cloud backend (Node.js/Firebase), and an AI layer to reformat questions and generate structured explanations efficiently. Here’s how I’d approach it: Build a smooth Android & iOS app with login, question flow, and instant results Create a backend to manage your question bank and handle AI processing Integrate an AI service (OpenAI/Claude) to rephrase and expand explanations within ~2–3 seconds Develop a simple admin panel or bulk upload script for your content Add analytics tracking (attempts, accuracy) with secure storage Provide full documentation for deployment and future AI provider switching I focus on clean UI, fast performance, and maintainable code so your app can scale easily as you grow your content. Your budget is noted—let’s discuss scope prioritization to deliver a strong MVP within it. Looking forward to collaborating! Best, Bhargav

Hi, Your app idea is great, but a full production build isn’t realistic within $350. I can, however, deliver a clean MVP that covers your core needs and is ready to scale. I’ll build a cross-platform app (React Native) with login, MCQ practice, and fast AI-generated explanations using OpenAI. You’ll also get a simple backend, bulk upload script (CSV/JSON), and basic analytics (attempts + accuracy). The code will be clean, documented, and easy to extend—so you can add advanced AI features later. If you’re open to an MVP-first approach, I can start right away and deliver quickly.
