While working for this company I was assigned to three outsourcing projects. First I was in Deceval, a trading company, doing an application to control the trading business in J2EE running in weblogic and a DB2 database. After Deceval, I was in Porvenir, a financial company, automatizing all transfer requirements; this project involves validation, liquidation and transfer of funds, by ACH. This solution was done with J2EE running in a OC4J application server and an Oracle database. And the last project was Claro, in this company I was part of a developing team, we corrected bugs and developed new functionalities for the call center application developed with Java EE5 (JSF, Eclipslink, EJB, JAX-WS, JAX-RPC and JAX-RS technologies) and storing the information in Oracle and sometimes reading information from AS400 through PCML.

It was a short project constructing a front end project to show all the Colombians financial credit history. This project was divided into three parts, one was to develop a web service to search people’s information on a COBOL database, a second part was to deploy, and divide the result in sections, and each section does an Ajax petition to search the information through the web service. The application runs through a tomcat application server but all the security and the authentication system runs through websphere. The application also searches information in a Sybase database.
