Crush

Overview

A location-first dating platform where the map is the product. Profiles surface in real time as people move, so the question stops being who matched last week and becomes who is close enough to meet tonight. Presence, matching, and chat all run on a live connection rather than a refresh cycle.

What was built

• Real-time presence layer that streams position updates to nearby users only
• Geospatial queries that keep the map responsive as the visible bounds change
• Live messaging built on the same socket connection as presence
