Project History
Audiophoria: Headless E-commerce Platform
https://audiophoria.euThe storefront is built with Next.js (App Router, TypeScript, Tailwind) and renders catalog and product pages server-side for SEO and strong Core Web Vitals, while cart, checkout, and account flows run client-side through secure API routes. WordPress and WooCommerce serve as a headless CMS via the WooCommerce REST API and WPGraphQL.
Key work included a custom PayPal gateway alongside Stripe, a loyalty rewards program, VAT-aware pricing, product search by name and SKU, consent-aware analytics and ad tracking, and media offloading to Cloudflare R2.
I also set up Docker-based local development, CI quality gates on GitHub Actions, and Kubernetes staging and production environments with automated deploys, then migrated and merged the live store data for a smooth launch.
