Senior Shopify developer in Cairo, Egypt.
I’m Mamdouh Aly, most people call me Dan. I’m a Shopify developer and front-end engineer with 9+ years in front-end, 8 years on Shopify and more than 264 Shopify websites behind me. I build fast, conversion-focused storefronts for fashion and lifestyle brands in Egypt, the Gulf, Europe and the US.
Shopify development, front to back.
Custom Shopify theme development
Online Store 2.0 themes built in Liquid: sections, blocks, JSON templates, metafields and metaobjects, set up so your team can edit the store without a developer.
Shopify front-end development
Clean, accessible HTML, CSS and JavaScript for storefronts: mega menus, filters, cart drawers, size guides and landing pages, built mobile-first.
Performance and Core Web Vitals
Speed audits and fixes for LCP, CLS and INP: JavaScript and asset optimization, lazy loading and removing render-blocking code.
Upsells, cross-sells and cart
Complete-the-look modules, cart upsells, bundles and popups that raise order value without slowing the store down.
Shopify Plus
Checkout Extensibility, Shopify Functions (discounts, cart transforms, delivery and payment rules), Markets for multiple countries and currencies, and Flow.
Headless and custom apps
Hydrogen and React storefronts, custom apps, theme app extensions and the GraphQL Admin and Storefront APIs.
Integrations
Payments (Stripe, PayPal, Paymob, Fawry, ValU), shipping (DHL, Aramex, Bosta), ERPs (Odoo, NetSuite) and marketing tools (Klaviyo, GA4, Meta CAPI).
Arabic/English stores for Egypt and the Gulf
Right-to-left Arabic storefronts, EGP pricing, cash on delivery, and local payment gateways and couriers.
