Olivier Van Steenlandt
Olivier Van Steenlandt is a Business Intelligence Professional who spent most of his early career assisting retail companies to get more value of their data using the Microsoft BI Stack (SSIS, SSAS, SSRS, Power BI).
As his first experience in the field (in Business Intelligence), Olivier worked as a Big Data Analyst using tools such as Hadoop and Spark.
In 2015 the focus changed to traditional data warehousing & reporting using SSIS, SSRS & MicroStrategy. A bit later, around June 2019, the opportunity arose to fill the position of BI Teamlead. In this function he was able to set up a hybrid BI Team (team members in Belgium and Belarus).
Early 2020, Olivier joined the dataMinds crew as a core member, assisting to organise several events.
Around April 2021, Olivier started a new position as BI Teamlead in another Retail Company to support business growth. Besides the challenge to help the BI Team grow and deliver projects on time, he started to use SSAS & Power BI.
When Olivier is not working there is a high chance that you find him on a football field, studying (BI Related), playing music (Saxophone / Piano) or cooking.
