"My experience with Muhammed has been great. We worked on a project that I had so many gray areas in and Muhammed helped me navigate them with ease. He went beyond just doing the job, but also kept providing feedback and what’s best for my business. He has a sense of ownership and responsibility that makes you believe it’s his own business that he is building an app for. I appreciate the collaboration, and will work with him again for sure."

Hi, I’m Afnan — a Wix Expert, Wix Specialist, and Certified Wix Velo Developer. I build premium Wix Studio websites, high-converting Wix ecommerce stores, and custom Wix web solutions that look stunning, perform flawlessly, and drive real business growth. Whether you need a Wix website redesign, landing page, custom form, or dynamic page, I deliver results that turn visitors into customers.
Most designers focus only on visuals, and most developers focus only on functionality. I combine both: pixel-perfect UI/UX design paired with custom Wix code, Velo functionality, API integrations, and mobile-optimized, high-speed performance. Your website won’t just look expensive — it will perform flawlessly, rank better, and convert visitors into loyal customers.
⚙️ My Technical Edge (The Velo & Custom Code Advantage)

• High-Converting Landing Pages – Designed to increase engagement and capture leads.
• Wix Website Redesign & Optimization – Upgrade your existing site for performance, UX, and SEO.
• Mobile-First & Speed-Optimized Performance – Ensure your site loads fast on all devices.
• Custom JavaScript & API Integration – For features Wix’s standard editor can’t handle.
🎁 FREE VALUE (No Risk)
I offer:
✔ Free homepage mockup OR UX audit before we start
• No pressure. No obligation.
• Just clarity and a visual direction to make your Wix website redesign decision easy.
📈 Proven Results & Case Studies
• Wix Ecommerce Store Redesign – New landing pages, dynamic product pages, and custom forms increased conversions by 20% in 30 days.
• Booking & Membership Platform – Built custom Velo booking flows and dynamic pages, boosting engagement by 50%.
• API Integration & Automation – Connected delivery and payment APIs, reducing manual work by 90%.
• Certified Wix Designer & Velo Developer – Delivering modern, secure, and accessible websites that rank and convert.
