Biography
I’m a previous hands-on business owner of a digital agency who led a team of 12 professionals, a US Navy veteran, and was also an award-winning creative & marketing director.

With over 20 years of experience, I bring more to the table than just User Experience, Product Design, and User Interface (UI) design. My strengths lean heavily on innovation, originality, and I am highly experienced with Figma concept design, prototyping, and design systems.

I also come with an added bonus of motion graphic skills, presentational skills, data analytics, coding HTML/CSS (it’s been a while, mind you), and more.
