Hey, my name is Mareka. I’m a Product Designer with over fifteen years experience in User Interface Design and User Experience Design. I have worked on over fifteen products and services directly or as a consultant and on a countless amount of web and marketing projects. My experience as a freelancer has given me deep insight into various companies, their workflows and the tools they use. I am able to bring a long term project to final design and also specialize in 1-2 month client oriented productions. I have led projects solo and with teams, bringing features to full cohesion and release.

I am a guru with agile product development on diverse technologies, design systems, design software, wireframing and prototyping tools. (See list on my CV)


I have led big and small teams from inception to launch

I am a Designer from the bottom of my heart

I want to create the best products that people love and companies profit from

I am always keeping the big picture in view

My designs are innovative, pragmatic and solution oriented
