Built a modern eCommerce storefront using Next.js for the frontend and MedusaJS as the headless commerce backend. The platform supports product browsing, localized storefront routing, and scalable commerce workflows powered by a PostgreSQL database hosted on Supabase. The frontend is deployed on Vercel, while the Medusa backend and infrastructure are hosted on Railway. Development was accelerated using Claude Code and a vibe coding workflow to quickly iterate on features, debug issues, and refine the full-stack implementation.
