  • FastAPI
  • React
  • TypeScript
  • PostgreSQL

Eleições Brasil

Live results from the official TSE count

  • TypeScript
  • Next.js
  • React
  • Fastify
  • PostgreSQL
Context
On election night the numbers change with every new batch and sit spread across races, states and municipalities.
What it does
Every new batch from the TSE, Brazil’s electoral authority, reaches the screen within seconds and without a page reload: ballot boxes counted, the two leading candidates side by side, a map by state and results for every race in each state and municipality. It also has a timeline of the night, state comparisons, the elected congress and a big-screen mode for TV. The numbers come from the official files unchanged, with no polling or forecasting.

LostAndFound

Tracking lost and found items

  • React
