Summary

Since 2018, I have been creating content people actually read. First as Head of Lifestyle at a Swiss news portal, later as a columnist, and today as the founder of my own coaching company.

I write newsletters, blog articles, and websites, create webinars, and plan content strategies. In doing so, I combine journalistic precision with marketing know-how and a fine sense for target groups. AI tools are a natural part of my daily work, from research and idea development to efficient text creation.
