About Constantino

Developing concise, efficient, and usable applications, articulating different trends in programming, testing, and UX.
My work quality benefits from my previous experience in cognitive ergonomics, knowledge management, psychology, systematization, and research.
I have experience and/or a weakness for companies working in research, education, personal development, health, or information, and/or with high capacity for innovation and social impact, whether non-profit or for-profit; but I love opening myself to new challenges...
