Hello.
I see this as a full-fledged OpenCart 3 build, where performance, clear product structure, and conversion really matter, especially for a glasses catalog with a lot of details. I would perform the setup from a clean installation, shape the product architecture (attributes, filters, variants) for scalability, and configure the theme for speed and UX, rather than for bloated visual components. Payment, shipping, SEO, and caching would be set up as part of one system, not as add-ons, with proper quality control before launch. I also document everything and hand over the store in such a way that your team can confidently manage and grow it without chasing the developer later.
