I'm Jan — a Helsinki-based Senior UX / Product Designer. I design digital products where complexity needs to become clarity. Over the past 10+ years, I’ve worked across healthcare, SaaS, FMCG, and consumer services — helping teams turn data, workflows, and ideas into intuitive and meaningful user experiences.

About me

I’m passionate about designing experiences that are not only visually refined, but genuinely useful — especially in complex, real-world contexts.

With extensive experience spanning from creating visually striking FMCG campaigns to developing gamified learning solutions, my work combines creativity with strategy.

My work sits at the intersection of user needs, business goals, and technical reality. I enjoy shaping ideas early, navigating ambiguity, and bringing structure to complex problems through research, interaction design, and iteration.

In recent years, I’ve focused on data-intensive and regulated environments within clinical research, where clarity, accessibility, and reliability are critical. Designing for these contexts has strengthened my ability to create solutions that reduce cognitive load, support decision-making, and build user trust.

At the same time, my background spans everything from fast-paced FMCG campaigns to gamified learning solutions — giving me a strong foundation in visual design, engagement, and storytelling.

I thrive in collaborative environments where design plays a central role in shaping meaningful, scalable solutions.
