Arnold Johansson is a versatile information technologist with a true passion for improving people, businesses, and organizations using "good tech".

As an early adapter of the Java language and its growing ecosystem, he is an outspoken proponent of secure Java Enterprise solutions and real Open Source software.

After nearly two decades as an IT consultant in many levels and verticals, Arnold now focuses on leading organizations on an architectural stable and efficient path of excellence.

Anders Welén embraced the object-oriented techniques of the Java language early in life, and later evolved to Java Enterprise specifications. As a true believer and evangelist of Open Source, he naturally discovered the JBoss Application Server, which led to years of providing expert consultation, training, and support for the JBoss and Java EE infrastructures.

As a result, Anders has seen a lot of both good and bad architectures, software solutions, and projects, most of which were a struggle from time to time due to performance problems.

Whenever Anders, through presentations, consultation, training, and (in this case) a book, sees that what he's trying to explain is getting through and the audience is picking up on it and adopting it for their own challenges, it gives him a warm feeling inside.
