I build polished, accessible frontend interfaces and digital signage experiences from Figma through production.
What I'm looking for
At ZetaDisplay, I design and develop responsive, production-ready interfaces and digital experiences for retail, transport, hospitality, automotive, healthcare and public services.
I translate Figma designs and functional requirements into reusable, pixel-accurate components using JavaScript, SolidJS, HTML, CSS, JSON and GSAP. I also integrate APIs, structured data and real-time feeds into customer-facing interfaces.
My work includes configurable digital menu boards for IKEA, live transport-data interfaces for Translink, cinema display systems for Filmhuis Den Haag, and venue display experiences for AFAS Live. I build for multiple screen resolutions, orientations and device platforms, including Samsung Tizen and LG webOS.
With a background in UI/UX and digital design, I bridge design and production through responsive design, accessibility, animation, design systems and component-based development. I collaborate closely with designers, developers, product owners and technical stakeholders through implementation and testing.
