I need a robust Shopify-based storefront built from the ground up. The site must be fully responsive, fast, and SEO-friendly while remaining rock-solid on security. Core functionality includes an intuitive product catalogue with search and filters, smooth cart and checkout, customer accounts, live order tracking, and a back-office dashboard that lets me manage products, orders, and inventory without touching code. Payments must go through Stripe and Telr in AED, with 3-D Secure and tokenisation enabled so customers feel safe. Please harden the store with SSL, secure authentication, and best-practice protection against XSS, CSRF, and other common threats. The theme has to switch cleanly between English and Arabic (RTL) and keep the same polished look on mobile and desktop. If you have experience wiring Shopify up to UAE shipping carriers, let me know; I may add that once the core is live. Deliverables • Custom Shopify theme (English + Arabic) tested on all major devices • Stripe & Telr gateways fully configured in AED and sandbox-verified • Product, order, and inventory dashboard set up and documented • Security hardening (SSL, secure auth, vulnerability checks) • Final QA pass, launch support, and short hand-off training Show me past work on comparable Shopify builds, especially ones that include multi-language or custom payment integrations, so I can gauge fit.
