About André

I enjoy developing robust, fast solutions for specific problems, avoiding dependencies on many libraries, preferring to work in clusters, and building my own database if necessary. I am not afraid of frontend development and, due to my previous activities, I know the problems that complex software introduces into an IT infrastructure so well that my solutions are usually simple and easy to maintain. 😉

I usually only need a terminal and can manage with a simple editor. I do not commit to colossal technologies or development environments and use them with caution.

A free workshop for IT infrastructure.
