ESA-tech is a multi-category e-commerce platform built for the German market, focused on delivering a fast, clear, and reliable shopping experience. The project went through several major design iterations, each aimed at improving usability, structure, and visual clarity for customers navigating a wide range of technical products. I worked on full-cycle UX/UI design — from building the information architecture and product navigation to refining the interface across multiple redesigns. The goal was to make the platform easier to browse, faster for customers to make decisions, and more competitive in a demanding European e-commerce space.
