In the most recent project I worked, Smartlunches https://www.smartlunches.com; My responsibilities included redesigning and implementing the current app, taking it to the next level and providing a design that worked on the desktop as on the mobile devices like smartphones and tablets without making a different app for them, instead just using an effective layout which adapts to the device and providing to the user a beautiful experience when they are planning the monthly meal plan for their children.
