About Stefan

Throughout my missions, for over 10 years, I have been handling data in all its forms. I integrate it, clean it, and make it available to users.
I am a curious generalist who dabbles in everything and believes that to make the right decision, the one that meets my client's needs, one must be able to propose several different solutions with their own characteristics.
In my missions, I have been involved in modeling/creating data warehouses/data lakes and integrating them into either a new environment or an existing one.

I am available for long or very short missions, depending on your needs.
