I want to give customers a smoother, more curated way to browse my Shopify store, so I need a custom catalog feature built directly into my theme or delivered as a lightweight private app—whichever you feel will integrate best with Shopify’s current API and my existing storefront design. Here is what I’m looking for: • A dedicated catalog page or section that loads quickly, is fully responsive, and keeps the look-and-feel consistent with the rest of the site. • Simple controls in the Shopify admin so I can create, edit, and reorder catalog groups without touching code. • Clean, modular code that follows Shopify best practices and works with Online Store 2.0 sections. • Clear installation instructions and a short hand-off video or screenshare walkthrough showing me how to maintain the feature. Performance and UX are top priorities, so please optimise for speed, lazy-load images where practical, and make sure the feature works on all major browsers and mobile devices. Let me know the approach you recommend—theme extension vs. embedded app—and include a brief outline of how you would structure the data and keep everything scalable. If you have examples of similar Shopify customisations you’ve built, feel free to share those links in your bid.
