    I'm an IT System Architect with 10+ years of experience in Oracle JDE ERP (also known as CNC), +10 in Unix-based administration, +5 in Database administration and +10 in Automation (Job Scheduling). I've worked as a Team Leader and Team Builder with less experienced system administrators that were working on and off shore. Not long ago, I led several Service Support Transitions for a big healthcare industry company as well as providing technical guidance for several IT Projects. Not soon after that, I improved myself as System Architect and as a Jr. Project Manager, while managing both Hardware Provisioning and Software Implementations, in the oil & gas and consumer products industries, jumping back and forth from consultant to freelancer. As of now, I've ventured into Information Security and Cloud Computing with high hopes and expectations, becoming a DevSecOps Engineer within six months; which allowed me to lead the initiative in Argentina as Cloud Engineer in ExxonMobil. I'm known for my problem solving skills and being a self-taught person, by proposing new solutions and process improvements. My greatest motivation is to work and travel, learn new cultures, new people and acquire new knowledge while taking new challenges.
