Antonio Hernández Díaz is an active believer in Open Source from Seville, Spain. He has more than 10 years of experience working for IT companies, and although he is a web development expert, he has always known how to deal with other kinds of projects or technologies, such as desktop applications, mobile projects, or optimizing databases.
Since 2011, he has been involved in the development of various GNU/Linux distributions, either as a member of the Guadalinex development team (an Andalusian regional distribution), contributing humbly with Linux Mint, or just learning how to make Arch Linux ISOs in his free time.
When he is not working on some of his projects, it's not strange to see him on top of a kayak.
Dennis Schwertel is a software developer from Germany with many years of experience in working with Linux systems and developing desktops and large-scale web applications for international companies.
