• In my experience I have had the opportunity to work in some roles, as an architect providing designs for solutions, as Technical leader directing a group of developers and as a Java developer.
• As architect I have established some guidelines for the development, investigating the tools and technology that better fits the solution, making technical agreements with clients.
• Also, I have worked in different companies related to Banking, Assurance, Government, Expense management.
• Good experience with the JEE stack: JSF, EJB 3, JPA and with different Spring modules (core, beans, data, batch, web).
• Recently working with a Microservices approach with spring boot and Java 8.
• Recent experience with cloud, using Amazon Web Services
• I have worked with different RDBMS such as Oracle, DB2, MySQL, SQL Server.
• Well known of web services approach, working with SOAP or REST services.
• Using the most common application servers such as Weblogic, WebSphere, JBoss, Wildfly. And tomcat as a servlet container.
• Good understanding and experience with Scrum.
• Improving performance of some features through reactive programming RxJava.
• I have elaborated many of the designs with UML using Enterprise Architect.
• For versioning I have used SVN and GIT, and for project management I have experience with Ant, Maven and Gradle.
