Software developer and Bitcoin expert

You talk to the person who does the work.

I have been developing software for many years and work independently in Switzerland. Making technical concepts understandable is part of my work.

I look for the simplest solution that solves your problem. My aim is for you to understand the result and be able to use it independently.
