E-commerce Website Development Needed

I need a full-featured e-commerce website built from the ground up. The primary objective is straightforward: showcase my products attractively and guide shoppers through a friction-free, secure checkout. I’m flexible on the underlying platform—whether Shopify, WooCommerce, Magento or another solid solution—so feel free to recommend whichever best balances scalability, ease of use, and long-term cost.

Key functionality must include:
• Product catalogue with categories, variants, stock control, and high-resolution imagery
• Responsive design optimised for mobile, tablet, and desktop
• Fast, intuitive search and filtering
• Secure payment gateway integration and SSL
• Customer account area with order history, shipping tracking, and wish-lists
• Basic on-page SEO structure and Google Analytics setup

Deliverables:
1. Fully operational website on my hosting or the chosen SaaS platform
2. Admin guide or short video walkthrough so I can manage products and orders on my own
3. One week of post-launch support to iron out any quick fixes

Clean code, clear documentation, and an eye for modern UI/UX will be the deciding factors. Let me know your suggested tech stack, estimated timeline, and any relevant live e-commerce links you’ve launched recently.
