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.
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.
