My first professional contact with Java. We created a web system to control problems of our users transport card. To create this system we used JSF 1.2 with Facelets, RichFaces and Ajax with a4j. For ORM we used Hibernate and all these were running on JBOSS server.

My first contact with IT. I used to extract information from a Data Warehouse using PL/SQL for the Telefônica marketing department focused on companies.

My industrial world. Here I had an intense contact with industries using Ladder language to automate big industry processes. I would use technologies like Rockwell Contrologix and Wonderware Archestra to control the process of many companies like Nestlé, Citrosuco, Goodyear, Cosipa, Cimpor, Tetrapak, Grupo Mitsubishi and others.
