I’m launching an online store and need a developer who can take it from concept to live site. The build must include a clean, responsive product catalogue, secure cart and checkout, and—because I selected “Social media integration”—tight connections to platforms like Facebook, Instagram, and X so I can promote and sell directly from my feeds. I’m comfortable with Shopify, WooCommerce, or a custom framework, as long as the admin area lets me update products and prices without touching code. Speed, mobile-first design, and clear, intuitive navigation are essential. Here’s what I expect at hand-over: • Fully functional front- and back-end e-commerce website • Payment gateway configured and test transactions completed • Seamless social media integration for sharing and optional social login • Basic on-page SEO and performance optimisation • A short walk-through or video so I understand daily operations Please share two or three live e-commerce examples you’ve built, outline your development approach, and give me your estimated timeline.
