Hi, I'm Alexandre Haederli
I tell stories with words — and sometimes a bit of code
I'm a journalist working for two Sunday newspapers in Switzerland. I'm part of a small team focusing on investigation and I like to dig into the data to find good stories to tell. Sometimes I make interactive graphics which allow our readers to explore the data by themselves. I code in javascript, python and php. I also do training for colleagues covering data journalism.

Tracking Stolen Bikes with GPS
We equipped bikes with a GPS system hidden in the light. We let bikes get stolen in three cities and followed the thieves. The result is available in three storymaps made with the awesome Knight Lab's Storymaps.js.

Looking for Vulnerable Infrastructures on the Internet
We used search engine Shodan to look for unsecure connected devices. We found a lot of private unprotected NAS and webcams. And also some SCADA system like the door looking system of one of the biggest football stadium in the country.
