Zusammenfassung
I am a Senior Data Scientist with 15 years commercial experience and 6 years education (MIT Sloan &
CSAIL Executive education AI - Implications for business strategy + Master's degree in Computer
Science from KTH).
My current employment is with Webstep AB in Stockholm as a Senior Data Scientist. In this role I give
strategical advice for C-level executives on implementing AI solutions for improved business value. I
also work hands-on in client projects giving expert advice on how to solve different machine learning
problems. A typical client project starts with meeting C-level management, discussing the
organizational process where they are interested in applying machine learning, for example how to
improve the accuracy of the ordering process to avoid over-stock. Then follows two to four weeks of
hands-on project work supporting the client team. The goal is to give the client's team of data scientists
a quick start, finding the most suitable feature selection methods, what models to use and tips on how
to avoid typical pitfalls of Spark such as out of memory, slow processing or excessive shuffling.
Previously I worked for Ericsson as a System Manager with the title of Senior Specialist. Before that I
was a professional services pre-sales consultant for Computer Associates with focus on sales, research
and development of customer adapted application monitoring solutions.

interface for an ECG analysis tool in Matlab.
Involvement
• The final task was to remove the SoBig worm and a couple of other viruses, which had infected
their computers. Since these types of viruses are not removed by ordinary antivirus software they
had to be manually cleaned out from the system.
