The problem Doodle Mate solves

Helps friends and people to communicate and strengthen their bond. People can have fun with their friends, by doodling cool objects and shapes. Doodle Mate helps lighten your mood and stress

Challenges we ran into

1. Cross Origin Issues.
   We were running two different servers (one on python Flask, other on PHP), so we needed our application to communicate with both the servers

2. Video calling
   This was our first time using the RTC API and stuff, we it was also challenging

3. Machine Learning (Image Classification)
   Doodle drawn by the users, needed to be give score... which requires ML algos (and no one in our team was great in that)
   Our project is not integrated with ML model right now, instead it is giving random scores to the doodles submitted
