Meet The CraftCodeCrew
This blog began in 2018, created by a group of students from DHBW (Duale Hochschule Baden-Württemberg) in Karlsruhe, Germany. At the time, we were all employed at major German enterprises, spending half our time on-site and the other half in university.
Originally called Billige Plätze (Cheap Seats) due to our habit of sitting in the back row of the classroom, the blog was soon renamed to CraftCodeCrew. After graduating in 2018, we pursued different career paths, and in 2020, three of us came together to found CraftCoders.
