When Marcin was a child, he used to break things - even his first PC. He has always wondered what caused the failure, especially when it comes to the blue screen in an operating system. This is how he started his adventure with quality assurance. At Netguru, Marcin takes care of quality and ensures that users get a reliable product. He likes sports activities, especially cycling and tennis. He is passionate about aviation which has a lot to do with testing, e.g. there is no place for mistakes in either of them.
