  Architect/Lead DeveloperReengineering of the existing ERP. Implemented SDLC and methodologies like MDA (Model Driven Architecture).Responsible the BPMN, UC, Sequence, MER, Deployment, Components, Package and Classes diagrams. Responsible for Deployment and Components Diagrams, when MER Diagram finished I was responsible for leading the Classes Diagrams with the Analysts/Programmers so we can generate the basic codes for implementation. All these work is done using Visual Paradigm 11.Responsible for implementation using JSF 2.1, Primefaces 5.0, JPA 2.1, Hibernate 4, JasperReports, iReport, JBoss AS 7.1.1, maven, Eclipse IDE (kepler) + JBossTools and git as a repository server.Projects were separated into two modules (two war files), one with business logic, persistence and services, the other client-side app, so it can be modified in the future with newer versions or other technologies like Vaadin, pure HTML/JavaScript with AngularJS or even SWING desktop apps. These technique avoids services of a particular module to stop and if problems arises only affects the upgraded/modified client-side app module.
