I want a clean, lightweight mobile app that lets my students browse all of my Sanskrit books and teaching material in one place. The core of the project is a well-organised library where every title can be downloaded as a PDF for offline reading. Simple navigation, search by keyword or category, and a pleasant PDF viewer experience are essential because most users will spend their time studying inside the app. Alongside the digital library I also need a straightforward way for readers to buy a printed copy. When someone taps “Order Book,” the app should collect shipping details, hand off to a secure payment gateway (UPI, card, or any reliable provider you recommend), and confirm the order for both the buyer and me. An admin area where I can upload new PDFs, update prices, and see incoming orders in real time will keep the workflow smooth. To judge fit quickly, please include links or store listings to past work that shows you have built e-learning, e-book, or small e-commerce apps before. Deliverables expected: • Cross-platform mobile app (Android first is fine) with PDF download viewer • Admin panel for uploading PDFs and managing orders • Integrated payment gateway for book purchases • Complete source code and store-ready build, with brief hand-over training Once these points are working reliably and tested, the project can be considered complete.
