I need an experienced Shopify designer-developer to polish my store for handheld shoppers. The site already runs smoothly on desktop, but the mobile experience—especially at checkout—needs work. Your main focus will be the checkout page’s design layout. I want the existing color palette updated so it feels cohesive with the rest of the brand, and I’d like prominent trust badges added in the payment section to reassure buyers just before they complete their order. While doing this, please ensure every element scales gracefully on common phone and tablet breakpoints and that load times stay lean. Deliverables: • Redesigned checkout page using the new color scheme, fully responsive on iOS and Android • Placement and styling of trust badges without affecting Shopify’s native checkout flow • Device & browser testing report confirming the page renders correctly and remains fast • Brief hand-over notes explaining where assets were added and how to adjust colors in the future A solid grasp of Shopify’s Liquid templates, CSS, and mobile performance best practices is essential, and I’m happy to provide brand guidelines the moment we start. Let’s make the last step of the buying journey look and feel as professional as the rest of the store.
