Domaines de compétence

I had my first programming experience at the university with Pascal language, and even though I had no previous computer knowledge I achieved the highest score of the class in the final project. Afterwards I had Java related topics and I decided to focus my career on it. After an internship in Brussels (2005) I started my career as a Java programmer and since then I'm working mainly with Java.

Experience covers requirement analysis, application design, generation of technical and functional reports.

Aug ’11 – Jul'13                                    Indra, Madrid, Spain                                               Analyst programmer

 

Indra is an important company, the biggest Spanish IT enterprise by number of employees. Indra is organized around three business areas: Information Technologies, Simulation & Automatic Test Systems, and Defense Electronic Equipment.

 

Projects and related technologies

 

At Indra my responsibilities were to add new functionalities to the applications I worked with, maintain the application code (bugfixing), generate functional reports and take a part in the migration project.

 

Log improvement

 

The telecom market is very dynamic and the incidents need to be solved as soon as possible. To identify where a problem is and determine the reason a good logging practices are very important.

 

I add to the layout new variables such as the session ID to be able to follow progress of the users. I used a filter to load the variables into the MDC. Improve the information given, correct the log level and monitor the timing was also necessary.

 

Due to the improvements of LogBack over Log4J, we decided to migrate to LogBack. The problem was that the Billing components use the Commons HttpClient project to send the data. HttpClient works with the logging interface provided by the Commons Logging package which does not support LogBack. I had to add several bridging modules to behave as if they were made to the SLF4J API instead.

Billing application

 

My main task was to monitor the user flow and ensure that the info retrieving in the application web was correct. I had to add a new functionality to the Billing tool in order to show the users the resume and details of their current salary balance. As the final TIBCO component called was different, a new request with new parameters was necessary. Also because the new request takes too long to be processed I had to use Ajax to avoid showing blank pages for too long.

Migration project

 

The mobile telecommunication company started to use a new Content Manager System. This new CMS needs the Portlet MVC framework to work, however all the web application had been developed with Struts 1.2 + Spring 2.

 

Due to the amount of logic and code one year and a half and team of eight were needed. We migrated the application to Spring Portlet MVC + annotations.

 

After that, my task l was to review the generated code to check that the application was steady, reliable and secure. This involved measuring the execution speed of the code, pointing out the bottlenecks, suggesting and implementing a more efficient thread safe solution.
