I need a full-featured e-commerce site developed from the ground up. The project is strictly website development and the end result should allow me to list products, manage inventory, handle payments, and track orders without relying on third-party marketplaces. The platform noted in my brief is “Penjualan.” If that name is unfamiliar to you, feel free to propose the closest match or suggest an alternative such as Shopify, WooCommerce, or Magento—whichever will best deliver a secure, scalable, and easily managed storefront. Key deliverables • Responsive storefront (desktop, tablet, mobile) • Product catalogue with search and filter capabilities • Secure checkout supporting major payment gateways • Dashboard for product, order, and customer management • Basic on-page SEO set-up and clean URL structure • Post-launch hand-over: brief documentation or walk-through so I can maintain the site myself Acceptance criteria The site must load quickly, pass standard security checks (SSL, HTTPS, no exposed admin paths), and display flawlessly across the latest versions of Chrome, Firefox, Safari, and Edge. Once the final build is approved on your staging server, you’ll migrate everything to my live domain and confirm that payments, emails, and analytics tracking all work end-to-end. Please outline your proposed tech stack, timeline, and any previous e-commerce builds that demonstrate relevant experience when you respond.
