I worked as the primary product designer within a small team, responsible for a large part of the product ecosystem. Over four years, we redesigned and modernized most of the company's legacy applications, gradually replacing fragmented interfaces with a unified and scalable digital system. One of the biggest challenges was designing for an unusually wide range of environments and devices — from small dental scanners and compact workstations to large Full HD touchscreen displays used in production. The system had to remain consistent and usable across very different screen sizes, input methods and working conditions. I designed the core experience from the ground up, defining the structure, workflows and interaction patterns across case management, production, 3D data and operational tools. The dental case became the central point connecting patient and prescription data, digital assets, manufacturing instructions, production status and history. The work was not only about creating new interfaces, but about establishing a scalable foundation that could replace years of accumulated legacy solutions. A reusable design system, common interaction patterns and a unified visual language made it possible to bring the same modern product experience to different applications and devices. This modernization also created an opportunity to introduce more advanced digital solutions across the company instead of keeping innovation limited to individual tools or teams. The result was a unified product ecosystem connecting clinical information, digital design and physical manufacturing — and a scalable foundation for bringing new technology and better workflows across the entire organization.
