This is part of my 3rd Year Project. I wanted to do something that could be used by real people. Then remembered my uncle who runs a catering business and he was looking for an app. I suggested him to go with PWA and convinced him to make it as close to an actual app and took the project.
Here is the Demo
From this app anyone could order catering services and admin could check the order details.
I had it running and received few orders from the app. (Currently the app is not used)
Lessons
Don't Create an APP for everything and think it will be the next facebook or zomato
Most of them in south when they go to caterers they want to talk in person to trust the person and it's a returning customer a simple whatsapp message would do and menu is still decided on call as it's too dynamic.
Anyways learnt flask and data modeling of firebase. Happy that it was useful atleast for few days.
