Senior full-stack engineer.
Next.js · commerce · backends.
I write the code that ships to production — App Router storefronts, headless commerce on commercetools and Shopify, TypeScript services with real observability.
Four capabilities. Picked deliberately.
Ten years of stack-hopping distilled into the four areas where I'm genuinely senior. Everything else is a tool I'll reach for when it's the right one.
Next.js & React, end-to-end
App Router, RSC, edge routing, ISR, tight Core Web Vitals.
Headless & composable commerce
commercetools, Shopify, Adyen, Contentful, Amplience.
Backend & API engineering
Node.js, FastAPI, GraphQL, REST, event-driven services.
Performance & observability
LCP/INP/CLS tuning, Datadog RUM, Sentry, Lighthouse CI.

Questions people ask before booking.
Who are you?
I'm Ibrahim Aly, a freelance senior full-stack software engineer. I've shipped Next.js App Router storefronts, Shopify A/B testing platforms, and commercetools work for brands including M&M'S, Mars, DEPOT, and Ocucon.
What do you specialize in?
Three things. (1) Next.js full-stack: App Router, React Server Components, TypeScript, Vercel. (2) Headless commerce: commercetools, Shopify, composable architectures, Core Web Vitals on real storefronts. (3) Backend & API engineering: Node.js, FastAPI, GraphQL/REST services, AWS, observability.
How can you help my business?
If you need to migrate to Next.js App Router, stand up a headless commercetools or Shopify storefront, build production backend services, or fix Core Web Vitals on a revenue-critical site, I own the delivery end-to-end and ship.
What's your development approach?
Clean TypeScript, tight feedback loops, real tests (Playwright, Jest), monorepo-friendly (Turborepo, pnpm workspaces), and production-grade CI/CD from day one. I build for the team that maintains it, not just the demo.
How do we start working together?
Send a short brief — scope, timeline, what's blocking you. I'll respond within 24h with a plan, a price, and the first call booked.
