Academic Notes Marketplace: Mobile & Web Apps

**Project Title:** Full-Stack Mobile App & Web Admin Development for Academic Notes Marketplace **Project Overview:** We are looking for an experienced full-stack development team or senior developer to build an end-to-end, syllabus-oriented Academic Notes Marketplace. The system consists of a cross-platform Mobile App (Android & iOS) for students and a Web-Based Admin Panel for creators/super-admins. --- ### Core Key Features (MVP Phase 1) **1. Authentication & Security Architecture** * Student OTP/Password sign-up & multi-role authenticated access (Student, Creator, Super-Admin). * Hardware/Session Limits: Enforce a strict maximum of 2 registered devices per student account with OTP-gated device removal. * Server-Side Entitlement: Zero client-side authority for payments; all document streaming tokens verified via server-side APIs. **2. Academic Content Hierarchy & Catalog** * Hierarchical Navigation: *Course $\rightarrow$ Year $\rightarrow$ Semester $\rightarrow$ Subject $\rightarrow$ Unit $\rightarrow$ Topic $\rightarrow$ Note*. * Categorization: Notes, Question Banks, PYQs, MCQs, Reference Materials. * Search & Discovery: Global multi-parameter search (subject, author, university, semester) with card listings. * Free Preview Engine: Lock full documents while allowing access to cover pages, table of contents, and 1–3 sample pages. **3. Payments & Monetization** * Single-note purchasing flow via Indian Payment Gateways (Razorpay / Cashfree / PayU) supporting UPI, Cards, NetBanking, & Wallets. * In-app purchase verification, real-time unlocking, and purchase history tracking. **4. Secure In-App Document Reader & DRM Mitigation** * In-App Rendering: Direct PDF streaming into a custom viewer (no raw PDF download or external sharing allowed). * Dynamic Watermarking: Per-user dynamic overlays displaying Purchaser Name, User ID, and Access Date across pages. * Protection Rules: Disable copy/paste, external file opening, direct printing, and OS-level screenshot/screen recording where technically feasible. * Reader Tools: Text search within document, pinch-to-zoom, page bookmarks, text highlighting, and custom user annotations. **5. Student Library & Dashboard** * Continue Learning tracker with completion percentage. * Organised tabs for Purchased Items, Saved/Bookmarked Notes, and Recently Viewed items. **6. Web Admin & Super-Admin Panels** * Content Creator Dashboard: Rich upload forms (metadata, subject mapping, preview page selector, PDF source, thumbnail, price setting, promotional discounts). * Super-Admin Portal: System-wide analytics (active users, total revenue, top selling notes, sales trends), user/creator management, platform content moderation, and copyright reporting management. --- ### Technical & Design Requirements * **Design Style:** Clean, scholarly, distraction-free UI with card layouts (Deep Navy/Teal palette). * **Mobile Stack:** Cross-platform (Flutter or React Native preferred). * **Backend Stack:** Node.js / Python / Go with REST APIs, encrypted storage for source documents, and expiring retrieval tokens. * **Performance:** Progressive page rendering in document reader without full file pre-downloads. --- ### Phase 2 Roadmap (Post-MVP Expansion) * Subject/Semester bundle packages & monthly subscriptions. * Interactive MCQ test module with auto-scoring and performance analytics. * Automatic versioning update sync for past purchasers. * AI Study Assistant integration (summaries, topic explanations, quiz generator). --- ### Deliverables Required 1. Complete Mobile App source code (Android & iOS) + published builds. 2. Production-ready Web Admin Panel. 3. Backend source code, deployment scripts, and API documentation. 4. QA/Testing documentation verifying DRM and device-limit enforcement.
