Turning an idea into a project through an authorized, traceable backend workflow.
FIAP Challenge · 2026
An innovation platform needs to distinguish who can contribute, assess, approve, and manage an idea. The difficult part is keeping permissions, lifecycle transitions, and the conversion into a project consistent across a mobile client and multiple data stores.
My work on this academic challenge covers the Java/Spring Boot backend, business rules, data relationships, Flyway migrations, and REST integration with the Kotlin/Jetpack Compose Android application.
OPERACIONAL, GESTOR, and LIDER have independent permissions. Android adapts the interface, but the API validates authorization and permitted state transitions. Hiding a mobile control is not the security boundary.
Project creation and the idea’s conversion are performed in one MySQL transaction, with at most one project per idea. This keeps a partial conversion from becoming a valid domain state.
MySQL is the transactional source of truth. MongoDB stores audit events and AI history. Gemini provides advisory, structured evaluations; it does not approve or reject ideas or change their status.
