I have a good experience in System Administration. During this period, I have taken on a range of assignments, from simple things like server setup, day-to-day technical operations, and database administration, to more elaborate tasks such as automated deployment and big-scale log processing. These assignments spanned multiple technologies. I am curious by nature, and proactive in the workplace. These characteristics, combined with my communication skills, allow me to interact beyond the core of my specialty, thus constantly acquiring new knowledge and skills relevant to my career.
