Sebastian Rottmann

Full-Stack-Developer | B. Sc. Business Information Systems

Only if the user side is understood in the development process, a very good software can be created. A very well programmed software that misses the application purpose does not add value. To develop a customer-oriented software is my goal.

Sebastian Rottmann studied Business Information Systems at the University of Applied Sciences and Arts in Hanover and finished his studies with very good grades. He already gained his first programming experience during his high school years. In addition to digitization projects at a renowned Hanover law firm, he consolidated his knowledge in software development, especially in the area of software testing at a Dax corporation and an IT service provider of the Sparkassen Finanzgruppe.

In addition to his expertise in software development, he has in-depth knowledge of customer relationship management and marketing, which was applied both theoretically and practically during his studies in Hanover and Ålesund (Norway).
