Profile

I am a professional with over 20 years of experience in various sectors of technology. Throughout my career, I've worked extensively with system analysis, development, integration, infrastructure, implementation, and system consulting. I specialize in specific techniques and tools, and I've also gained some exposure to others through specific projects or even as a hobby.

I graduated in Engineering in 2009, but my contact with computers began in childhood. I value classic, stable, and reliable solutions. I am cautious with new trends: I believe trust is earned over time and after passing various stress tests.
