I’m preparing to launch a small online shop focused on selling customized abstract art prints, with plans to expand the catalogue later. I already have branding assets (logo, color palette, basic copy) and now need a complete, production-ready e-commerce solution— NO WordPress. No Shopify. The fastest route is fine: if you have a previously finished e-commerce code-base you can legally reuse, feel free to adapt it, as long as the final result meets these concrete requirements: • Custom CMS — product, category and page management through a clean admin UI. • Secure checkout via PayPal and Stripe, triggering automatic transactional emails (order confirmation, failed payment, dispatch notice). • SEO-ready architecture: human-readable URLs, editable meta title/description, auto-generated XML sitemap, plus clear hooks for future on-page optimisation. • Responsive front-end optimised for fast page loads and best-practice security protections (CSRF, XSS, SQL-Injection). • Email system for newsletter opt-ins (simple list capture is enough). I’m open on the underlying stack—PHP/MySQL, Node/Mongo, Django/PostgreSQL, or another proven combo—as long as it delivers the functionality above, remains easy to maintain, and carries no vendor lock-in. Please make sure the finished code is clean, documented and ready for me to take over. Let me know which existing framework or in-house platform you plan to adapt, how you’ll integrate the payment gateways, and roughly how long hand-over will take once designs are provided. Bid must include final proposed price.
