Projects I've worked on:
Mamãe Pingo
Residency
Mamãe Pingo is a mobile application designed for parents and caregivers of children aged 0 to 5, offering personalized scientific information, developmental milestone tracking, community features and an immunization calendar. During my participation in the TIC Residency program, I contributed to both the technical and organizational sides of the project. I helped develop new mobile features, integrated APIs, modeled data structures and collaborated on UX/UI prototypes. I also supported project management using Scrum, organizing sprints, defining priorities and improving the team’s workflow.
Dairy Farm
Volunteer
Dairy Farm is a web application developed to display and analyze dairy farming data in a clear and interactive way. I worked on building a responsive interface focused on usability and data visualization, creating reusable components and improving the user experience. The project was developed in collaboration with Professor Eduardo Noronha, a specialist in data analysis for the dairy sector.
Malucas Awards
Personal
Maluca Awards is a personal project created in 2024 as a playful parody of the VMA. It was built as a voting platform for a group of friends, where users could log in, vote across different categories and choose the winners. At the end, we hosted a small event to reveal the results and celebrate together. It was a fun and interactive project that combined technology with entertainment.
