What I'm looking for

I’m looking for a Senior Product Design role where I can own multiplatform UX end-to-end, build and evolve design systems, and partner with product teams to validate through research, workshops, and usability testing—especially in enterprise B2B contexts.

I’m a Senior Product Designer with a decade of cross-disciplinary practice—spanning end-to-end product design, enterprise B2B UX, visual identity, and traditional illustration. I’m comfortable owning multiplatform experiences across Android TV, web, and mobile, while also turning executive data into clear presentation visuals.

In my most recent role, I was the sole designer on a multiplatform product ecosystem delivered to MVP. I led product discovery (requirements gathering, UX research, persona creation, and competitor analysis), defined information architecture and user flows, and translated business concepts into scalable product structure, workflows, and system logic.

I also bring a research mindset from my biomedical engineering and computer science background, including EEG-based work on emotions and user interfaces—an approach that informs how I validate design assumptions through feedback loops and user testing. Across consulting and enterprise environments (from Roche leadership visualization work to Siemens’ B2B SaaS logistics platform), I’ve built design systems, facilitated workshops, and created reusable UI patterns that teams can scale.
