Build Responsive Digital Product Store

I’m launching an online shop that sells digital products only—downloadable files, full courses, and any future items that don’t require shipping—so the entire experience has to focus on instant, secure delivery after checkout.

The site must be:
• Fully responsive, looking and working great on phones, tablets, and desktops
• Easy for me to manage: add new products, update pricing, and view sales without touching code
• Integrated with a reliable payment gateway (Stripe and/or PayPal) that releases the download link or course access the moment a transaction clears
• Equipped with customer accounts where buyers can log in, re-download their files, or pick up their course progress

I’m open on platform choice—WordPress + WooCommerce, Shopify with a strong digital-goods app, or a modern headless stack—so pitch whatever you believe will handle secure file hosting, automated emails, and scale for future growth.

Please include:
• The tech stack you recommend and why
• A brief outline of your build timeline, from design through launch
• Links to at least two stores you’ve built that deliver digital products

I have branding and product assets ready to hand over, and I’m available for quick feedback throughout the project. Let’s build something smooth, fast, and conversion-friendly.
