The concept of transforming paper menus into digital formats accessible via QR codes inspired me to develop a comprehensive PaaS solution for restaurants that would provide just that. This platform, now serving over 1,200 restaurants and attracting 150,000 monthly visits from end users, equips hospitality businesses with essential tools for creating and managing their menus ensuring compliance with current regulations.
