Curriculum Vitae Ingo Karkat topic home

I'm a professional software developer with a strong interest in software engineering practices. My fascination with electronics and programming started early in the home computer age; I found a satisfying place in various open source projects, and I enjoy working in large, complex projects in a multi-cultural professional environment. With my commitment to the highest standards of quality and craft, I enjoy steadily improving on the code and watching the software grow and adapt.
