I want to launch an e-commerce marketplace dedicated entirely to digital products—think software, templates, ebooks, music, and similar downloadables. Buyers should be able to browse items, add them to a cart, pay securely, then immediately receive their files. On the seller side, creators need an intuitive dashboard to upload products, track sales, and manage payouts. A built-in user reviews and ratings system is essential. Shoppers must see authentic feedback on every product page, and sellers should be able to respond to reviews. If you have a proven approach for preventing spam or duplicate ratings, let me know—content moderation is important to me. Core functions I expect: • Account creation with email and social sign-ins • Product listing flow for digital files (version control and file size limits configurable) • Secure payment gateway integration (Stripe or PayPal preferred) • Automated fulfillment that delivers the correct download links after successful payment • Search, category pages, and basic filters for easy product discovery • Review & rating module tied to verified purchases • Mobile-responsive UI and clean, lightweight codebase Tech stack is flexible; however, I’ve worked with Node/React and Django in the past, so either direction is fine if it suits rapid development and future scaling. Please outline the approach, estimated timeline, and any comparable marketplaces you have built. I’ll test the first upload-to-purchase flow end-to-end before sign-off.
