Custom E-Commerce Website Build

I need a developer who can craft a fully-custom e-commerce site from the ground up rather than relying on Shopify or WooCommerce templates. The store has to feel fast, modern and scalable, with clean code that I can maintain long-term.

Core features I must see working flawlessly:
• Product search and intuitive filtering
• Customer reviews that display by product and feed into overall ratings
• Secure payment gateway integration (credit cards and popular wallets)

I am happy to discuss which language or framework you feel will deliver the best performance and security, as long as it supports those must-have features and is future-proof.

Please send over a link to two or three live stores you have built yourself, noting the stack you used, along with a ball-park cost and timeline so I can understand your approach. I will review portfolios as they arrive and get back to shortlisted freelancers quickly so we can refine the scope and milestones together.
