Shopify Expert Needed — Fast Theme Build, SEO, Core Web Vitals, CLS-Free Pages

I am looking for a highly experienced Shopify expert to help customize and build out a Shopify website/theme properly. This is not a beginner project. I need someone who deeply understands Shopify, Liquid, theme structure, page templates, SEO, speed optimization, and how to build clean, stable pages that do not create layout shift problems. My budget is up to $15/hour maximum (we will start at $10 and work our way to $15 when I am sure you're good at what you do), and that rate is only for someone who is genuinely experienced, fast, and knows what they are doing. Please do not apply if you are learning Shopify, need constant guidance, or cannot work efficiently. Important Requirements: * Must be available during CST / Central Time working hours for communication and updates. * Must have advanced Shopify theme customization experience. * Must understand Shopify Liquid, theme templates, sections, metafields, apps, and Shopify’s limitations. * Must understand SEO basics and how Shopify pages should be structured for search. * Must know how to build a fast Shopify website with strong Core Web Vitals. * Must understand CLS and know how to make sure every page passes layout shift checks. * Must be able to follow detailed instructions without needing repeated explanations. * Must be detail-oriented. Small spacing, layout, mobile, SEO, or performance mistakes matter. * Must be able to create and adjust Shopify templates quickly without wasting time. * Must test work before sending it to me. * Must communicate clearly and provide timely updates. Very Important: If you create an issue, break something, cause layout problems, damage SEO structure, slow the site down, or ignore instructions, you will be expected to fix the issue on your own time. I am not paying for avoidable mistakes or rework caused by carelessness. I need someone who takes ownership, checks their own work, and does not send unfinished or sloppy work for review. What You’ll Do: * Customize Shopify theme templates based on detailed instructions. * Build clean, reusable page templates and sections. * Make sure pages are responsive on desktop and mobile. * Preserve SEO structure, headings, internal links, metadata, schema opportunities, and page speed. * Prevent CLS issues by properly handling images, fonts, sections, banners, icons, and dynamic content. * Troubleshoot Shopify theme issues quickly. * Deliver clean, tested work within agreed timelines. How to Apply: 1. Start your proposal with the phrase: “Shopify Pro Ready” so I know you read this carefully. 2. Confirm that you are available during CST / Central Time working hours. 3. Confirm that your hourly rate is $10-%15/hour or less. You will start on $10/hr and when I am sure, we'll build you up to $15/hr gradually. 4. Share at least 3 live Shopify websites you personally customized or developed. If you did this with a team, which parts did you work on? 5. Briefly explain your Shopify experience, especially with Liquid, theme templates, SEO, speed optimization, and CLS/Core Web Vitals. 6. Tell me how you test your work before sending it to a client. 7. Tell me what tools you use to check page speed, SEO, and layout shift. Only serious Shopify experts should apply. I am looking for someone reliable, technical, fast, detail-oriented, and easy to work with.
