Developed as the first proof of concept (PoC), the project involved close collaboration with front- and backend engineers to conceptualize the service's foundation, user stories, and user flows. These user flows were initially translated into low-fidelity wireframes, which evolved through multiple feedback loops into high-fidelity wireframes. After further evaluation, the high-fidelity wireframes were refined into a final prototype in Figma, serving as the basis for development.
