Challenge: A client wanted to launch a digital-goods marketplace with many sellers, secure downloads and built-in growth loops.

What we built: Vendor onboarding and storefronts, secure signed download delivery, cart and checkout with coupons and gift/referral flows, order history and refunds, plus an admin panel with RBAC and audit logs.

Impact: The platform scaled to many vendors on shared infrastructure while keeping delivery secure and checkout fast.

Stack: Laravel, Stripe Checkout, signed URLs, Blade, CSP-hardened front end.
