I am a big fan of using and helping others use agile/scrum and writing and helping others write easy to maintain code.
I am passionate about writing easy to maintain code and I tried to help the programming community with my courses on this subject.
I'm also a big fan of Agile and SCRUM and how you can build motivated, happy teams around it.
I've worked on a lot of types of projects. From small to medium projects where I was the only developer to medium and big projects in teams of 30+ people.
Besides being a developer, in the last five years I've also have the Scrum Master role, or led the process of applying Scrum inside the team.
I am currently writing mostly Java, and have certifications in PHP and Scrum.
