About the project

Avatar da Saúde is a B2B health-tech platform designed to help companies manage the wellbeing of their employees and families. The app centralizes health indicators, gamified missions, wearable integrations and chronic patient monitoring into a single experience.

I was responsible for the complete UX/UI redesign of the mobile product, working closely with the product and engineering teams to evolve the interface from a functional prototype into a polished, scalable and emotionally engaging experience.
