DerFredo aka Thomas holds a degree in Business Economics, but has been a data explorer and a developer at heart ever since the days of dBase and Turbo Pascal. He touched his first SQL Server at V6.5, used covering indexes before they became a feature and joined the PASS community in 2006.

Thomas has been developing in Navision/Dynamics/Business Central systems for quite some time (since 2001, one year before MS acquired Navision), got his hands on R in 2014 (the year before MS bought Revolution Analytics), on the Power Platform from 2020 and the Arduino world from 2024 on. He has worked for ISVs as well as end-user companies, as a developer, consultant, accidental data engineer and is an author for data-related articles as well as a speaker at data events across Europe.
