  Building a team

  During my career I have built the data function from scratch in 3 different tech companies. Each case had it own specifics: SaaS and PaaS, office based and remote, same country and multiple time zones

  Data science

  I have been working with data one way or another during the last 15 years. I call my self a data professional but I always focus on the decision making and how data can help stakeholders or systems to make the right decision. Sometimes just getting the data straight is good enough (not that it is easy) and most of the times a pivot table with the right data would do the trick. Not all the times though :)

  Product analytics

  How the product is being used? What are the different user segments? How are these different when it comes to loyalty, monetisation and overall value? Which ones are the price sensitive? Some of the questions that I or my team as been dealing with in the past 10 years or so
