About the Author

Matthew Urban
Matthew Urban

born in Chicago (USA) in 1986, moved to Cracow (Poland) in 1990.

He started programming when he was eleven. As a kid, he loved to prepare static webpages in pure HTML and CSS. In high school, he learned Pascal, C, MS Access, and SQL and started to create simple games in Flash. As a student, he was hired as an intern - more precisely, as a Junior C++ developer - to support a team that was building a CAD application. Next, before he graduated, he started full-time work on a start-up project (medical sector) in which he was the first Java developer in the company. He graduated from the University of Science and Technology in Cracow with a master's degree in software engineering. After that, he decided to move on and gain experience in commercial projects. When he worked in the medical, financial, and tourism sectors, the most exciting project for him was the BPM System. Some of the products he created are used by clients such as BMW, ABB, and Mercedes-Benz. He gained over ten years of experience working as a full-stack Java developer in different types of technologies. Currently, he is interested in AWS and different usages of machine learning algorithms in the financial sector.

In addition to that, he is a happy husband and father of two lovely daughters. He loves to ride his bike, walk in the mountains, and play chess.
