I build the systems companies run on.

Three bookable products behind one basket: hotels through the Hotelbeds bedbank, guided tours with their own availability calendar, blackout dates and per-guest-type pricing, and airport transfers priced by route and vehicle class. Rates and cancellation terms are captured at the moment of booking, so a later supplier change can't alter a confirmed reservation. Payments run through Stripe and PayPal behind one gateway interface, with exact integer arithmetic on every multi-currency amount. Around that sits a promo engine with targeted campaigns, generated codes, eligibility rules and redemption reporting, plus customer records with leads and notes, templated notifications, PDF vouchers and revenue reporting — the whole platform in English, German and French.

A multi-sided logistics platform for Egyptian merchants, serving vendors, delivery agents, warehouse staff and customers. Parcels move vendor to warehouse to customer across an eleven-state lifecycle, with QR-verified custody at every handover and OTP confirmation on delivery. Underneath it, a credit/debit ledger reconciles cash-on-delivery collections, shipping fees and order subtotals into vendor wallets, settled as payouts or collections. I built the backend, the admin and customer portal, the Flutter app for vendors and agents, and a Shopify app, now published on the Shopify App Store, that pulls merchant orders straight in.

A Shopify app that turns a local courier into a shipping option at checkout. Live rates come from the Carrier Service API, orders forward to the courier automatically, and as the parcel moves the app writes fulfillments and delivery events back to Shopify, so the order reads Fulfilled and the customer gets tracking. Built with least-privilege scopes, all three GDPR compliance webhooks, a webhook-health monitor that warns merchants if orders stop arriving, and a retry worker with backoff.

Showroom and shop for a Cairo house that carves furniture and objects in natural stone, in English and Arabic with a full right-to-left layout. Each piece comes in sizes and stones, and every combination carries its own price, stock and lead time. Visitors build an order and submit it as guests: the server reprices every line, saves the order once however often the button is pressed, issues a reference number and hands it to WhatsApp for the team to confirm. Behind it sits an admin for products, variants, stones and images, an order inbox with CSV export, printable QR tags for expo pieces, email alerts and daily summaries, and invite-only admin accounts. It runs on Cloudflare Workers, D1 and R2 for close to nothing a month, and shipped in time for the La Marchée design fair.

Enterprise ERP/CRM used by 6,000+ employees across two business units, covering sales, HR, finance, learning and supply chain. I own the leads, deals, units, HR, learning, supply chain and reservations domains, across both the Laravel backend and the Next.js front end.

National initiative to modernise Egypt's customs operations. Microservices backend and registration APIs for brokers, agents and stakeholders, behind multi-factor authentication.

Two national systems. The National Archives platform digitises Egypt's public records, with role-based access and a custom permission model. The National Silos platform governs grain logistics on IBM Cloud Paks, with Node.js services reading weighbridge scales at silos nationwide.

Backend for a Dutch e-commerce platform selling refurbished home appliances. Product and category management, warehouse and inventory tracking, and the order and stock handling behind it.

Online store for a Germany-based brand selling dates, nuts and dried fruits. Built the storefront, product structure and performance work, with Stripe payments and DPD shipping automation. Seven collections, a wishlist and quick-view flow, and a checkout carrying Klarna, PayPal and Apple Pay.
