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.

A few projects I was involved in
Swiss Administration Procurements
Each year the federal administration purchases more than five billion francs worth of goods and services from private companies. This application, created with the help of Datastory, shows what type of goods and services each department spends its budget on. It also reveals the administration’s biggest suppliers.
