Shopify E-Commerce Web App

I need a full-featured e-commerce web application built on Shopify. The goal is to launch an online store that is ready for real customers on day one—fast, secure, and optimized for both desktop and mobile browsers.

Because I’ve chosen the Web application route and specifically selected Shopify as the platform, everything you deliver must stay within Shopify’s ecosystem: Liquid templates, Theme Customizer settings, Apps, and APIs. Custom code is welcome as long as it’s clean, documented, and maintains upgrade-safe best practices.

Here is what I expect at minimum:
• A custom or customized Shopify theme that reflects my brand style, renders responsively, and passes Shopify’s performance checks.
• Product, collection, and navigation structure set up so I can begin uploading inventory immediately.
• Payment gateway and shipping rules configured for my region (details provided after hire).
• Core apps or native features activated for analytics, SEO basics, and abandoned-cart recovery.
• A brief hand-off guide or video showing me how to add products, fulfill orders, and tweak content.

Acceptance criteria
1. Store passes Shopify’s checkout test order and yields no critical errors in the Shopify Theme Inspector.
2. Google PageSpeed Insights score of 90+ on mobile for the storefront home page.
3. All text and images are editable through the Shopify admin without additional code changes.

If you have recent Shopify builds and can meet the above scope quickly, I’d love to see your work and discuss timelines right away.
