We make all the development process, starting in the UML design and ER Modeling, going through the scripting and testing, and finishing with the implementation and final documentation. We work with open source applications and we generally make open source projects. We develop information Systems in PHP code, mainly with MySQL, PostgreSQL, but we can also work with other DBMS. We use de PHP as the controller, the DBMS for the model, and for the view we use HTML5 and pure Javascript, JQuery, bootstrap, and other JS libraries. As for the Framework, we use our own in house built Framework but we can work with CodeIgniter too. We can start a project since the beginning, or we can make specific modules for existing projects.
