About

Muhammad Elsayed

Full-stack & e-commerce developer. I build web applications and online stores with a focus on speed, conversion, and clean code.

Story

I build for the web and teach how it works.

I'm a full-stack and e-commerce developer. I build custom applications with React and Next.js, online stores on Shopify and WordPress, and I spend a lot of time on the details that decide whether a site sells: speed, conversion, and clean code.

Alongside the client work, I'm a Teaching Assistant at Mansoura University, where I studied Computer Science and graduated with Excellence and Honor. Teaching keeps the fundamentals sharp and pushes me to explain the work clearly.

What I care about is building things that perform. A store that loads fast and converts, an app that's clean to run, and code that the next person can actually read. That's the bar for every project.

What I do

Skills built on real store and app work.

I work across the stack: storefront, frontend, backend, and the performance details that decide whether a site sells.

End-to-end web apps with React, Next.js, Node.js, and PostgreSQL — clean code, fast interfaces.
CRO & conversion
Conversion rate optimization: cleaner storefronts, better product pages, faster checkout, fewer abandoned carts.
E-commerce builds
Shopify and WordPress storefronts built around conversion, with themes, Liquid, and clean customization.
Speed optimization
Page speed and Core Web Vitals work: caching, image optimization, and clean code that loads fast.
APIs & integrations
Integrations, custom APIs, and connecting stores to the tools and data they depend on.
Teaching & writing
