Agile learning and problem solving. That's the fun part
I started out designing and animating in a totally legitimate version of Photoshop and Macromedia Flash, and trying my hand coding games in Game Maker. I ended up drawing a liking to web development and exploring other media, such as photography and filmmaking.
After a few years studying International Marketing, and starting my own agency, the Business / Marketing stack started taking form. Hobbies became work, and here I am - using every bit of experience to solve problems and find new ways to improve businesses in any possible way using communication, technology and digital tools.
It doesn't really matter if I know it, I just need to learn it. Same goes for tennis. My serve is horrible.
