    I'm a Software Engineer with extensive experience managing all aspects of the software development lifecycle in different business types, such as: health, insurance, sales, marketing and internet business. I also have planned and developed IT Infrastructure projects. After 8+ years of experience, I feel that my professional expectations are more related with technical aspects. In programming I always try to write simple, readable, efficient, consistent and maintainable code since I believe that here reside the true return of investment. I enjoy greatly working in "self organizing teams". In my free time I like reading books or watching movies with my wife.
