About Kristina

I’m a Product Designer with 5+ years of experience turning complex products and workflows into clear, intuitive experiences.

I’ve worked across SaaS, iGaming, and other digital products, designing everything from data-heavy dashboards and complex user flows to scalable design systems and responsive interfaces.

I enjoy bringing structure to complexity: understanding how a product works, identifying friction, and designing solutions that feel simple and predictable for users. My approach is system-oriented and focused on creating experiences that can scale as the product grows.

With a background in journalism, I’m naturally curious and quick to learn new industries. I’m comfortable taking ownership of projects and collaborating closely with product teams, developers, and stakeholders from discovery through delivery.
