Overview

I have more than 30 years of experience in software development and computer science:

• 10 project years of Data warehousing, business intelligence (BI) and data science
• 6 project years Java platform
• 5 project years GPU computing and C++
• 4 project years in frontend development
• functional programming since 1994

Remark

Dipl.-Inform. is an (now outdated) german academic degree and can be translated as "diploma of computer science". It took at least 4.5 years (9 semesters) and is similiar to a masters degree.

My method

I am an agile and pragmatic software developer and optimize productivity and code quality with innovative methods.

Customer focus

The customer is the "mother of the project."

Pragmatic and agile

Selection of "best practices" from the existing process models (XP, agile, SCRUM, Kanban), adapted to the project, the team and the task.

Iterative and incremental

Software consists of knowledge. A large part of this knowledge is created during the project and therefore the requirements change.

Team-oriented

Only as a functioning whole a team is successful.

Test driven

Automated tests as early as possible.
