I need a Shopify expert to refine my store’s functionality and build a set of custom forms. My priority is performance and usability rather than visual tweaks, so I’m looking for clean, reliable code that fits neatly into my existing theme without breaking anything else. Scope of work • Diagnose current theme to spot any bottlenecks or redundant apps. • Implement the agreed-upon functionality upgrades—whether that’s smoother navigation, a faster checkout, or tighter integration with select third-party services. I’m open to your recommendations. • Design and embed custom forms (think product enquiry, returns, or wholesale signup) that capture data to the admin or our chosen CRM. Forms must validate properly, look consistent on mobile/desktop, and send confirmation emails. • Test across modern browsers and devices and document any theme edits so I can maintain them later. Acceptance criteria 1. All new functionality runs in production with no console errors. 2. Custom forms submit, store, and email data accurately. 3. Core Web Vitals remain at or above current scores. 4. A short hand-off guide explains where you edited Liquid, JS, or CSS. If you’ve built similar Shopify features, please share a quick example and outline how you’d approach this upgrade. I’ll review proposals as they come in and aim to start immediately.
