“𝐈’𝐦 𝟒𝐟𝐭 𝐢𝐧 𝐦𝐲 𝐰𝐡𝐞𝐞𝐥𝐜𝐡𝐚𝐢𝐫 — 𝐜𝐚𝐥𝐥 𝐦𝐞 𝐚 𝐦𝐢𝐝𝐠𝐞𝐭 𝐬𝐩𝐢𝐧𝐧𝐞𝐫.” That’s right. I’m not just a web developer — I’m the story behind the screen. Hey there! I'm a front-end focused full-stack developer with 5+ years of experience creating beautiful, accessible, and scalable digital experiences - and a personal journey that has shaped me into someone who doesn't shy away from a challenge. ⚡️ 𝗪𝗵𝗮𝘁 𝗺𝗮𝗸𝗲𝘀 𝗺𝗲 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁? I was born with a rare bone disease (osteogenesis imperfecta). Growing up, I faced physical limitations - but I refused to let them define me. Where others saw obstacles, I saw the perfect setup for a comeback. Today, I code with purpose, design with empathy, and build with precision. Whether it's a portfolio, a SaaS dashboard, a landing page, or a full-stack app, if it's not perfect, I'm not done. 🍽️ 𝗪𝗵𝗮𝘁 𝗜 𝗯𝗿𝗶𝗻𝗴 𝘁𝗼 𝘁𝗵𝗲 𝘁𝗮𝗯𝗹𝗲: ✅ Pixel-perfect Frontend (React, Tailwind, native CSS) ✅ Solid Backend foundations (Node, Express, MongoDB, PostgreSQL) ✅ Responsive design, accessibility, & blazing-fast performance ✅ Complex state management (Redux), API integrations, Auth systems ✅ Mobile-first thinking with React Native & PWA features ✅ Modern tooling: Git, Agile, CI/CD, testing, DevOps basics 𝗕𝘂𝘁 𝗺𝗼𝘀𝘁 𝗼𝗳 𝗮𝗹𝗹, 𝘄𝗵𝗮𝘁 𝗜 𝗿𝗲𝗮𝗹𝗹𝘆 𝗯𝗿𝗶𝗻𝗴 𝘁𝗼 𝘁𝗵𝗲 𝘁𝗮𝗯𝗹𝗲 𝗶𝘀 𝗰𝗼𝗺𝗺𝗶𝘁𝗺𝗲𝗻𝘁: I treat every project as if it's my own. I ask the right questions. I care about the details. I never settle for "just work" - it has to feel right. 💎 𝗠𝘆 𝗽𝗿𝗼𝘂𝗱𝗲𝘀𝘁 𝘄𝗼𝗿𝗸? maqraah.de - a complete Arabic Quran learning platform that I built from scratch: code, UI, UX, vision. It's alive - and people benefit from it every day.

People who value clarity, open collaboration, and clean results. If you're looking for someone to just “get it done,” that’s not me. 🚀 𝗪𝗵𝗮𝘁’𝘀 𝗻𝗲𝘅𝘁? I’m building towards a bigger vision: starting my own Arab-led tech company that makes a global impact. But today, I’m here to help you level up. 🌍 𝗠𝘂𝗹𝘁𝗶𝗹𝗶𝗻𝗴𝘂𝗮𝗹 𝗕𝗼𝗻𝘂𝘀: 🟢 German: „Ich bin ein leidenschaftlicher Webentwickler und habe Spaß an der Umsetzung von Visionen in funktionierende und schöne digitale Produkte.“ 🟢 Arabic: أنا مطوّر ويب شغوف، أحب تحويل الافكار إلى واقع رقمي جميل ومفيد.
