Other times I will be working on a cool complex VBA project for automation. I am all about automation. Everyday I work with data and analyzing it to see what it can tell me. I enjoy the challenge of being inventive and designing a solution to complex problems. Because I do this on a daily basis, I am constantly learning things I didn't know.
