Jewelry E-Commerce

I want a completely self-coded e-commerce site built from the ground up. The store will feature mostly jewelry, with clothing and other accessories following close behind, so the design has to feel modern and minimalist while still letting the products shine. Nothing off-the-shelf—no external themes, plugins or apps. Every feature, front-end and back-end, must live inside one clean, well-documented codebase that remains fast even with 10,000–20,000 SKUs.

Core expectations
• Lightning-fast, mobile-first storefront that embraces a modern, minimalist aesthetic and scales effortlessly.
• Custom admin for product, inventory, customer, order and return management.
• Native integrations for RazorPay, PayPal, PhonePe and UPI.
• Automated shipping workflow: rate calculation, label generation, tracking updates and return authorisations.
• Built-in AI helpers—smart search, product recommendations and basic merchandising rules—coded directly, not layered through a third-party library.
• Marketing stack baked in: on-page SEO controls, email marketing engine, and direct hooks to Google, Facebook, Instagram, Pinterest and YouTube for catalog feeds and conversion tracking.
• Complete GDPR-/privacy-compliant data handling, clear documentation and handoff of source code.

Acceptance criteria
1. Page-speed score above 90 on both mobile and desktop (Google Lighthouse).
2. Admin user can create, edit and bulk import at least 20k products without timeouts.
3. Successful test transactions on all four payment methods.
4. End-to-end order flow—from add-to-cart through refund—demonstrated on a staging URL.
5. SEO, email and social integrations verified via live API calls.
6. Source pushed to a private Git repo with setup instructions.

Once these items pass, the project is complete.
