Message

At Dell Technologies, I designed an internal developer portal for 13.8K engineers, bringing tools, releases and infrastructure provisioning together. Provisioning went from months to minutes, and developers now do 80% of it themselves.

At Wallester, I led the first unified design system across web, iOS, Android and marketing, including a brand layer for white-label clients. I also set up an AI-centered workflow to keep the platforms consistent.

For Jaleco, a financial platform for physicians, I designed an AI workflow that takes the product from request to production. AI builds screens from my design system, and nothing ships without my review.

Earlier at Jüssi (Ogilvy), I managed a 26-person UX team and led UX across concurrent client projects. My background also includes product design for e-commerce, fintech and mobile apps, supported by a degree in Automation and Control Engineering.
