Term paper alongside with an internship scholarship focused on the portability of PVANET - a virtual learning environment of the Universidade Federal de Viçosa (UFV), for the Android platform. I worked on the requirements analysis and gathering with the Departamento de Informática (DPI) and the Diretoria de Tecnologia da Informação (DTI) in a project named UFV Mobile. I was responsible for the architectural modeling of the app, in which I used some of the main software design patterns in Android: Model View Presenter and Clean Architecture. The application was developed using the Test Driven Development (TDD); therefore, having an extensive testing routines and high robustness. The project developed is being homologated by DTI and soon it will be used by UFV students

The objective of this internship was to develop a clock-in system under the Android platform. By bering one of the main developers of the project, I worked on the development and the enhacement of new features. I developed automated tests using JUnit, Robotium and Roboeletric. Later on, by using a tool called Jenkins, I was responsible for the implantation of Continuous Delivery and Continuous Integration. Again, with Jenkins and the support of static code analysis such as FindBugs, PMD and CheckStyle, I developed an automated code review to guarantee a better code robustness. With that, it was possible to decrease the number of errors applying an intense routine of integration testing before the delivery of the final product.
