Experience

Scheduling Library Rooms

I was part of a team that developed software that aimed to solve a scheduling problem in the study room of my old university.

We used Java with the PrimeFaces library to develop the project, where several concepts were used, such as Agile methodologies and design patterns. The software communicated with the university's internal system to validate user logins and controlled reservations respecting all rules imposed by the university regarding the use of rooms.

I configured the entire development environment with Maven and PrimeFaces and coached the entire team on how the technologies work.
