Digital health design combines interdisciplinary teamwork with a human-centered approach. By using iterative prototyping and participatory co-design, I look at how technologies like machine learning and computer vision can address real healthcare needs. The focus is on the relationship between people and technology, practical applications, and ethical aspects. My aim is to create assistive solutions that make patient and clinician experiences better. I am especially interested in UX, service design, accessibility, and using gamification to encourage engagement.
