Who I Am
I didn't start from a CS background. I started from Photoshop. I spent years learning design before I ever touched code — color theory, composition, visual hierarchy, the kind of things that make you obsess over every pixel. Then one day I opened a text editor, typed some HTML, hit save, and saw it appear in the browser. That moment changed everything. I realized I could build the things I'd only been able to imagine. From there I taught myself everything: JavaScript, React, Next.js, Flutter, Node.js — not through a degree, but through obsession, late nights, and building real things for real people. Since 2022 I've been working as a freelance developer, shipping production-grade web and mobile apps for clients across Egypt and the Arab world. Now I'm also studying Computer Science formally, and it's filling in every gap I didn't know I had — algorithms, systems, the theory behind decisions I was already making by instinct. What makes me different is the combination. I can build and design — and I can teach both. I understand why a design decision was made, which means I implement it right, push back when something won't work, and suggest something better when it matters. I've shipped apps with real users, real payments, and real consequences. And I've explained all of it in Arabic, to thousands of developers who needed someone to speak their language. If you're looking for someone who treats your project like it's their own — let's talk.

What I Do
01
Frontend Web Development
With 5+ years of experience, I build dynamic, user-focused websites and web apps using React and Next.js. Clean code, fast load times, accessible markup — production-ready from day one.
02
Mobile App Development
Cross-platform mobile apps with Flutter targeting iOS and Android from a single, maintainable codebase. Real-time features, complex state management, Firebase integration, and smooth 60fps UIs.
03
Portfolio Websites
Professional portfolio websites with a built-in content management system — update your projects, skills, and info without touching a single line of code. Built to impress clients and recruiters alike.
04
UI/UX Implementation
Pixel-perfect translation of Figma designs into working, animated, responsive code. Every hover state, every micro-interaction, every spacing detail — exactly as designed, nothing lost in translation.
05
Photo Editing
Two years mastering Adobe Photoshop and Canva — product photo retouching, social media visuals, creative compositions, and brand-consistent imagery that actually converts.
06
Logo & Brand Identity
Over three years crafting distinctive logos and brand identities with Adobe Illustrator and Canva. From concept sketches to final vector assets — a brand identity that speaks before you say a word.
