Worked on an application that help you discover people with similar interests.
Behind the UX:
1. Users are matched based on the interests (hashtags) they add.
2. Actively allow them to add or remove their interest and placing them at top on explore section.
3. The application had premium users too and we ensured that they get enough attention.
4. Heavily images focused layouts with only essential information at display.
Wishing you all a very happy new year.
