Apart from all competences that I possess and consolidated overall through the years of my professional live I need to emphasize the following one: focus on customer expectations and early anticipation of what/how the system will do and behave, driven by an BDD approach with incremental delivery of software.
In order to achieve that, a special effort I've being doing on the type and quality of software tests needed to be undertaken by the developer. For that sake, and in short terms, we have unit tests (project safety net with Mockito/Powermock frameworks) that allows refactoring without fear, junit integration tests (speed up development and get to know better the system integration modules) and acceptance tests (get to know better the system as a whole in business terms, using Cucumber as a tool for that matter). Of course, a critical judgment needs to be taken in order to not spend to much effort on tests maintenance compromising production code delivery.

In my career, technology skills, play a great deal, always trying to architect the best technological solution that fits a certain problem to solve.

Things that are inner characteristics of myself:
►Team player maintaining a relation of trust with co-workers and everyone is involved.
►Committed to customer targets.
►Hard working who is focused on achieving excellence.
►Fast learner with a learning curve being more steep as my experience is consolidated over time.
