About This Project
**The Problem:** A premium traditional menswear brand needed to deploy its flagship Eid 2026 collection with exact ad tracking to maximize ROAS and a purchase flow heavily optimized for mobile conversions. **The Solution Architecture:** We constructed a headless commerce engine on Next.js 16 and Supabase. To guarantee 100% accurate attribution for marketing campaigns, we implemented the server-side Meta Conversions API (CAPI) alongside robust client-side Pixel deduplication and an automated Google Merchant XML Feed. The storefront UX features dynamic conversion rate optimization (CRO) elements, including a sticky mobile add-to-cart bar, intelligent cashback announcement logic, and real-time urgency/scarcity badges. **Measurable Results:** Successfully launched the Eid 2026 collection with a complete, full-stack ad attribution pipeline, generating immediate revenue and providing a frictionless mobile checkout experience.
