// About

I connect users, product, technology and teams to turn complexity into clear digital experiences.
I'm Deniz Topuz, a UX Lead based in the Netherlands. I combine UX design with a technical front-end background.
My strength is not one individual skill. It is the ability to connect disciplines and move between strategic, technical and design perspectives.

UX designer with over thirteen years of experience in complex digital products, working as UX Lead, UX architect and epic owner of a design system. I research how people use software, turn what I learn into accessible interfaces and prove the idea with low- and high-fidelity interactive prototypes. My background combines UX and UI design with front-end development, which makes it easy to work with product owners, developers and stakeholders across teams.
