About Sebastian

My professional profile is distinguished by a solid combination of technical experience, effective leadership skills, and commitment to the training of human talent. Throughout my career, I have demonstrated skills in managing support teams, proposing technological solutions aimed at continuous improvement, and contributing to the strengthening of the digital infrastructure of the organizations in which I have participated. My approach is characterized by responsibility, operational efficiency, and results orientation in collaborative environments.

While my experience has been mainly linked to technical support, my training as a computer engineer has allowed me to develop a comprehensive vision of the technology sector. Currently, I am looking for new challenges that allow me to expand my field of action towards areas such as software development, process automation, and data analysis, in order to continue providing value from a multidisciplinary perspective and aligned with the strategic objectives of companies.
