Who is behind this membership site?

My name is Petri Kainulainen and I have over 20 years of experience from building web applications with Java programming language. I am specialized in architecture design, software development with Spring Framework, and automated testing. I am also writing a blog where I publish tutorials which help you to write better tests, or use a specific library or framework.
