    I want a complete Android e-commerce application built from scratch. The core of the project is a clean, intuitive shopping experience that consumes my existing REST APIs, parses JSON responses efficiently, and presents products attractively through XML-based layouts. To succeed you’ll need to: • Hook the app to my REST endpoints for product listings, cart actions, checkout, and user accounts. • Structure all network calls responsibly, with solid error handling and graceful offline states. • Respect Android’s latest permission model when accessing camera, storage, or sensors; the app must never crash on denied permissions. • Keep UI components modular and reusable—Material Design guidelines are a must so the catalog, product detail, and ...

    ...tech stack, coding, testing, and packaging the final installer. You’re free to work in a language you’re most comfortable with—whether that’s C#, Java, Python, Electron/JavaScript, or something comparable—as long as the result runs smoothly on Windows and can later be adapted for macOS or Linux if sales demand it. Robust error handling, an intuitive UI, and clean, well-commented code are must-haves so I can maintain or expand the product later. Deliverables • A brief proposal outlining two or three software concepts and their revenue potential • Approved concept translated into UX mock-ups and a technical architecture overview • Fully developed desktop application with executable installer and complete source...
