With years of functional experience in the computer field, from UNIX systems and networking, to different programming languages and frameworks, not only those teached in college.
Versatility and ease to face any project (with or without having the necessary skills) and with the recurring idea of optimization and performance in all I do. Even without enough knoledge to submit a task, having to learn it or to come up with a coherent solution, it has to be in a sensible way. I prefer to racking my brains and resolve a nest of if's applying Boolean Logic and Karnaugh, than to leave them in a redundant or an ordinary way, even if it still "works".
I'm a big fan of DRY (Do not Repeat Yourself) and KISS (Keep It Simple, Stupid!) philosophies, not only in computer science but in life.
