Cover image for Designed and developed a modern

Designed and developed a modern 3D interactive website concept for Freej Swaeleh, a Kuwaiti restaurant brand. The goal was to create a premium digital experience that combines Kuwaiti cultural identity with modern 3D web design, while making it easy for customers to explore the restaurant, menu, branches, gallery, FAQs, and ordering options. What I built • Interactive 3D website experience • Modern responsive UI/UX • Restaurant menu & dish showcase • Branch/location section • Food gallery • FAQ section • Online ordering concept • Mobile-responsive experience • Smooth animations and interactive elements AI Integration Concept I also designed the concept for an AI Restaurant Agent that could be integrated into the website to provide 24/7 customer assistance — answering menu questions, recommending dishes, providing branch information, helping with reservations/orders, and more. Live Demo: https://eajajhossain.github.io/freej-swaeleh/ Note: This is an independent concept/prototype created to demonstrate the potential digital experience and is not an official Freej Swaeleh website.
