Score: 4.7/10 (Innovation: 5, Technical: 6, Documentation: 2, Utility: 3)

Similarity is an experimental dating/connection site inspired by early-2000s OkCupid, using collaborative filtering-style matching based on shared tastes rather than swiping. It features a custom in-memory match engine built in Java with a React frontend, deployed on PaaS infrastructure.

Target audience: general consumers interested in non-swipe dating; backend developers curious about custom match engines
