I want to launch a dedicated e-commerce platform that sells digital products, with “Handphone” as the initial flagship item. The site has to feel like a modern marketplace where buyers can browse, purchase, and immediately receive their files, while future vendors can sign up to offer their own downloads later on. Core features I need built include secure user accounts, a clean product catalogue, instant file delivery after payment, coupon support, and a straightforward vendor dashboard that lets contributors upload, track sales, and withdraw earnings. Stripe or PayPal integration is essential for check-out, and the whole front-end must be responsive so customers on mobile or desktop have a smooth experience. Please use a framework or stack you’re comfortable maintaining long-term—Shopify app, WooCommerce with digital-download extensions, or a custom React/Laravel combo are all fine so long as updates and scaling are straightforward. When you send a proposal, briefly outline the stack you’d use, any similar digital marketplaces you’ve launched, and your estimated timeline for an MVP that can go live.
