Hi! My name is Michael Simons. I live in Aachen and create software for a living. You can read more about me on the "About me" page. This blog mostly contains posts about Java and Softwarearchitecture with a strong focus on the Spring eco system.
Below is a list of featured posts and a collection of talks. Featured posts are either part of a bigger series, have a relevance somewhere else or are just posts I like.
