I am an enterprising person with years of experience in different sectors, but all related to IT, who love challenges and do not give up easily. Very detailed and self-taught every day, I never stop learning and I have a special gift for people. I have been able to adapt to the different IT plans of the companies for which I have worked. Additionally, I have a great capacity to analyze information and experience in team management.
