Kalisi

The Bay Area food map that's already done the scrolling for you. Trending spots arrive pre-pinned and heat-ranked, with nothing to save or import before the map is useful.

Every pin is a real spot creators are posting about. Color and size track its heat score.

Problem

Food recommendations were scattered across social posts, and existing apps asked for saves or friend invites before they became useful.

Decision

Resolve each video to a real place with an address and source links, then weight creator count, video count, views, and recency into one map score.

Result

More than 100 Bay Area spots on a live map, plus a weekly Heat Index that separates places gaining momentum from older viral hits.

Under the hood

A React and Leaflet frontend runs on a Fastify API. Postgres stores places, mentions, and heat history. Ingestion, deduplication, scoring jobs, and the API run on Railway.
