Hello! Hyojin is a Berlin-based Product Designer focused on building AI-driven product experiences, with 6+ years of experience simplifying complex digital products and turning high-constraint systems into human-friendly experiences.

I work at the intersection of product design, systems thinking, and AI-assisted workflows, helping teams not only define better user experiences but also shape how those experiences can be built faster and smarter with emerging tools and technologies.

Currently, I'm designing the global checkout experience at Mercedes-Benz, improving how users navigate one of the most critical moments in the customer journey.

You can often find me mentoring and being mentored in the design community, while experimenting with new creative possibilities through vibe coding.

What my colleagues say

  • Hyojin applied her knowledge and her get-things-done attitude to produce really high-class results, all of which in my opinion exceeded expectations of her age group & experience

    Design Director @Selfapy

  • Her approachable and open nature makes her a joy to work with; she is always willing to listen, share, and support her team.

    Product Owner @Mercedes

  • Not only does she understand the strategy and user experience design, but she can also approach UX design from a design system perspective.

    Design Manager @Favorite Medium

  • This collaborative setup of UX team and developers working togeher in real time meant that fixes were not only discussed but implemented and reviewed on the spot, which helped speed things up and ensured everyone was on the same page

    QA Engineer @Mercedes

  • Hyojin enabled the team to focus on most of the low-cost/high-benefit issues that have troubled the product team for a long time.
