Example Application to compare Attributes

[morismc09]

Hello everyone, there's an idea on my mind which includes the following elements:

• A website where users can enter specific attributes like hobbies which are then secretly being stored and encrypted in the Nillion network
• Other users can find other people with the same hobbies while the matching happens via a secure matching mechanism which does not disclose the hobbies, but just shows if people are matching by their hobbies

Now I'd like to know...

• how I can make sure that the hobbies of the user who enters them are not being exposed either to my server nor to anyone else
• how the matching can be done without disclosing information about the user#s hobbies
• how a huge amount of matching calculations can be done in parallel to deliver quic results
• which tech stack you would use to create such an application.

Did anyone here implement anything similar in the past?
