about
I got started in UX after completing Flatiron's UX Design program in 2020, and received a B.S. in Entrepreneurship & Innovation from Butler University. I formed my own design agency and have since worked with over 100 international companies ranging from small startups to Fortune 50 companied like T-Mobile and GE Healthcare. During that time I've worked on pretty much every aspect of the design process from idea to launch.
When I'm not designing, I spend as much of my available time as possible traveling to new countries experiencing different cultures, and bringing my camera to different parts of the world. The more immersed I can get in a new place, the better. I find having those experiences helps me better understand people from different backgrounds and able to empathize with them when I'm tasked with creating or improving an experience.
