Web Application

LiteBerryPi provides a platform for people to show that they are present with others, when they aren't able to physically be there.

It is a unique way to communicate with others and show that a user cares in a fun way that isn't a text or email. Quarantining further limits social interactions, and Lite-Berry Pi will bring friends and loved ones together despite not being able to physically visit.

LiteBerryPi is an ASP.NET Core restful API built on an MVC framework. users can register and login via a SwaggerUI on the apps homepage. Then use the generated token in postman to create and send designs!
