About the author

Joakim Wassberg is a software developer who for the past 30 years has worked in a variety of areas, such as security in financial systems, secure payment systems, and as a specialist and architect of development methods.

Throughout his career, he has always worked with education in programming, from introducing children in a playful way to take their first steps, to teaching senior developers a new technology or development methodology, and from company training to university courses. Since 2014, together with his wife, he has run the company Arthead, which works exclusively in education and educational development.

I would also like to thank my wife, Susanne. Her input, suggestions, and ideas have been brilliant, and without her support, writing this book would have been much harder. She did not know anything about programming before I started writing this book, but now she knows quite a lot. If she can learn it, so can you.
