Working with data to me is just like playing with puzzles all day long. I love being able to take an ocean of data, reshape it, model it into information, and present it in such a way that helps people better understand their world.
I'm a huge Power BI user and am just as happy playing with M, DAX, or the Visualization layer. I also love teaching, especially when I can take concepts that seem extremely difficult and present them in a way that is easy to understand and still lets their elegance shine through.
