I plan to launch a sleek, mobile-first Shopify store and need a developer who can take it from blank theme to live site within 7 days. The focus is on speed, clean UI, and rock-solid SEO so the shop is discoverable from day one. Core requirements • Build the shop in Shopify’s latest Online Store 2.0 framework, styling it with modern Liquid, HTML5, CSS3, and lightweight JavaScript. • Ensure every page is fully responsive and scores well on Google PageSpeed for both mobile and desktop. • Configure a secure, fully tested payment gateway (Stripe and/or PayPal; open to other recommendations) so customers can check out without friction. • Optimize on-page SEO—meaning logical heading structure, meta tags, alt text, and clean URLs—so products rank quickly. • Set up essential analytics and tracking (Google Analytics 4, Facebook pixel) for performance monitoring. • Hand over a concise guide so I can add products, edit content, and manage orders myself after launch. Acceptance criteria 1. Store passes Shopify’s theme check with no critical errors. 2. Mobile PageSpeed Insight score of 80+ on the homepage and a sample product page. 3. Payment gateway processes test transactions successfully. 4. Site handed over on or before day 7 with admin credentials and documentation. If you have a portfolio of fast-loading Shopify builds—or can point me to one—let’s get started.
