Kids Jewelry Dynamic-Pricing Storefront

Built a luxury jewelry e-commerce platform with three proprietary modules: (1) a live-gold-price engine that recalculates product prices daily by gram weight via ­cron-driven API calls; (2) a mobile-exclusive Tawk.to chat layer that auto-loads only on handheld breakpoints to boost Core Web Vitals; and (3) a full Progressive Web App shell with service-worker caching and install banners for iOS/Android. The stack also includes AR try-on, engraving options, QuickBooks sync, and COPPA/GDPR compliance.
