My friend Edy Cruz built SoroJá, a free tool that shows people across Brazil where to find the right antivenom after a venomous bite or sting.
The idea started with a scorpion sting tragedy. Edy read a news article about how, in an emergency, it was surprisingly difficult to find out which nearby hospital had the required antivenom.
Official information existed, but people had to search through PDFs on government sites to find it. With SoroJá, they can share their location or search by city and see where to go.
Edy is not a developer, but he built SoroJá with Claude Code in just a few days. The project is now open source, and he hopes it can find a permanent home within a public health institution that can maintain it.
Soon after launch, Edy went viral - news outlets across Brazil covered SoroJá, and he was even interviewed on national television.
Edy has joined almost every Haavn’ Fun session this year from home, the office, airport lounges and, on occasion, even the jungle! He says what he learned there helped him build SoroJá.
Haavn’ Fun is our weekly gathering for people in tech, business, creative fields, and anyone curious about AI. We get together and learn by building.
Edy, thanks for inspiring us with the things you build.
