About.
As a UX/UI Designer, I supported the creation of an application dedicated to personalized fitness and nutrition programs. The project was built in close collaboration with the client through ideation and design iteration workshops, progressively validating each key feature to ensure consistency and relevance in the user journey.
In parallel, I designed the admin platform to enable teams to manage content autonomously and intuitively.I also produced all desktop and mobile mockups, as well as interactive prototypes to facilitate validation at each stage of the project.
There was strong ongoing collaboration with the tech team to ensure technical feasibility, quickly adjust proposals when needed, and optimize implementation.
The collaboration with the brand designer was asynchronous, with regular alignment on visual elements. Together, we defined the shooting briefs and graphic formats to be integrated into the approved templates, ensuring strong consistency between the brand identity and the UI.

Challenge.
The main challenge of this project was working with the client’s marketing teams, who were not familiar with digital constraints.
It was necessary to adapt to their availability and compensate for the lack of a Digital Project Manager.
The key task was to frame and validate each step of the process in collaboration with all involved teams, ensuring clear and continuous communication.
Special attention was given to the proper implementation of the admin platform to ensure the client could manage the content autonomously and efficiently.
Result.
Client Alignment
& Design Validation
Workshops conducted with client and brand teams.
Main features validated and mockups approved without major rework -ensuring full integration of the new visual identity across all mobile and desktop templates.
Admin Autonomy & Content Management Efficiency
Content creation, update and publishing tasks completed autonomously by the marketing team without any technical support through an intuitive and purpose-built admin platform.
Design-to-Dev Velocity
Mockups validated without major rework, delivered across sprints
→Tech / PM team: ratio of approved designs vs. revision cycles, reflecting the quality of client workshops, tech alignment, and prototype-driven validation process.
