Kjeld in a few words

I’m an AI specialist with 15+ years of software development experience and academic degrees in Artificial Intelligence and Data Science. With a varied background in both technical and commercial roles, I help organizations innovate and solve problems on many levels. I enjoy working on multiple, diverse projects at the same time: helping small and large organizations identify opportunities for time-saving, money-saving, quality-raising and/or competitor-beating applications of AI. And building them.
