I am a doctor in astronomy, former support astronomer in a major observatory in Chile, and developer of tools and apps for astronomical observers since more than 10 years.

I am dedicated at filling the gap between researcher-level tools and general-public apps. This is both for researchers to make their tools more accessible, and "amateurs" to access professional-quality tools. I love citizen science, and for that one must help those worlds to communicate. This will also help teachers and their classrooms all over the world to play with free and open material.

Thanks a lot for your support!

🌃 Made with love from the Alps.
