Lunna is an app that provides assistance on women’s health. The app learns over time about user choices, preferences, and symptoms using Machine Learning, allowing user improve life quality.



Worked collaboratively with the team, and managed a tech team of 10 UX designers, researchers, and software engineers. I had daily stand-up meetings via video conference with the development and design team in Brazil. I needed a quick MVP (minimum viable product) but ready to scale version of the app. I proposed an initial Sprint to quickly study and run spikes with potential infrastructures and scalable technologies. We collaboratively opted for Elixir and Postgres due to the balance of fast development and scalability. We deployed an interim version of the app every 2 weeks on a Sprint. The prototypes were tested in different times with final users by the UX team in Brazil coordinated by me.


SCRUM and Kanban


I coordinated the design and development changes and prioritized them. I run more than 2 workshops in different stages of the app designing and developing. The user research helped me delimitate and also polish the app. In parallel, I ran different Google Forms to confirm and discover more information about my target needs. In one of my first Google Forms, I got +300 answers in 3 days without any massive web campaign. I also led some discussions at web groups to discover and understand the needs of my target. I was impressed because everybody I talked got super interested in the app, willing to donate their time to help me, and also participate in the workshops, surveys and beta test.
