It's a simple endorsement app where someone can praise another person for a job well done and endorse it. It is built using Javascript, Html , CSS and firebase for storage. A PWA(progressive web app) that can be used on your smartphone too!
Simply go to settings(three dots) when you open the website on your mobile, and choose "add to home screen" or "install". Then you can use this app on your smartphone! Voila!
Happy Coding!
