My current e-commerce site needs a thoughtful refresh that goes beyond a simple facelift. I’m looking to add entirely new sections, modernise the look and feel, and introduce functionality that keeps shoppers engaged all the way through checkout. What I’d like done • New pages & sections: an expanded product catalog with clear categories and smart filtering. • Design & layout updates: a responsive, mobile-first UI that aligns with our brand and loads fast. • Functionality enhancements: a smoother cart and checkout flow plus a robust user-account area where customers can manage profiles and track orders. Tech notes The store is built on a standard LAMP stack, but I’m open to solutions in WooCommerce, Shopify (Liquid), or a React-based headless setup if it meets the goals above. Clean code, SEO-friendly structure, and performance optimisation are must-haves. Acceptance criteria 1. Product catalog pages display all current SKUs, category pages are filterable, and search returns accurate results. 2. Cart and checkout work flawlessly on desktop and mobile, with payment gateway and tax/shipping rules intact. 3. User account section lets customers view order history, edit details, and reset passwords without errors. 4. Pages score 90+ on Google PageSpeed for mobile and pass basic accessibility checks (WCAG AA). Hand-off Please deliver source files, any theme or plugin customisations, and a short deployment guide so my in-house team can maintain the site going forward.
