The problem Huddle-911 solves

Protects Doctor's income by leveraging On-Chain anonymity. It also ensures healthy competition among doctors thus helping decrease ridiculously high medical fees.

Challenges I ran into

1. I decided to not use Iframe coz the aesthetics just didn't match, but that choice came with many challenges the team was really helpful with their quick replies on Discord too.

2. The biggest huddle was to create a means of communication between the client and doctor while maintaining the anonymity of both. But Push Notifications came to the rescue so it all worked out in the end and the communication between client and doctor no longer needed the involvement of off-chain identities like email or phone number.

3. Last but not least was choosing a Db, but choosing one of the centralized services would have yet again compromised the whole idea of this Dapp. Thus we landed on Polybase a decentralized database written in typescript-like language, pretty awesome.
