Thorsten Harbig was born on August 30, 1977. He grew up at Lake Constance in southern Germany. He studied computer science, spent 7 months in Belgium working on his diploma thesis, and finished his master's degree in energy savings on mobile phones from Aalborg University in Denmark. Since then, he has worked as a software consultant for companies in the finance and automotive sectors and as a trainer for Java EE courses.

Since the last 3 years, Thorsten has shifted his focus to project management, beginning with small software projects using agile methods, and lately working on software and hardware projects, covering the entire process as follows: starting with an idea, working on requirements, performing the design and realization, and planning the manufacturing and packaging at the end.

Thorsten always looks for new, interesting topics to work on, and wants to share new achievements with colleagues and others who are interested.
