    Chile - Tests: 6

    I like the mental challenges , constantly learning about my field of study as far as possible trying to implement it in my workplace, and this accomplishes that new knowledge are firmly anchored in the unconscious to effectively implement them , which is why I need and Seeking a work of great complexity. I have excellent insight and understanding of how the various mechanisms work computer. I've always enjoyed optimize computers, servers, and platforms taking full performance. I enjoy the work intellectually motivating and present continuing challenges to keep systems running. Monitoring , configuration , backup, maintenance of software systems is something I've done since childhood from the time that my father bought the family an Atari 800XL , I was always in charge of " family support " and the more I understood my family about computers and technology . After the acquisition of an Acer 486SX began my self- learning MS -DOS (command line) and 3.11 WINDOWS since at that time the computers he brought books in Spanish about 500 p. describing the operation of the various operating systems. In continuing this trend now beginning to internalize in no specific areas of my studies as they are CSS , HTML , PHP , C + + , JAVA and Android. I have a high work ethic implying dislike wasting time or have other recreational activities in the workplace, which is a low mental challenge during the day. This is also reflected in the face with the same energy as both pleasant activities less conspicuous activities in which the worker is required. Downtime at work and try to avoid it if no other attempt take out time to study or read about topics of interest to help me improve or develop as a professional in the area of Information Technology and Telecommunications. The information technology and communication are so great and changing universe that is necessary for professionals continually perfections and investigate on their own. I enjoy getting books in English in Pdf. file the Internet when something does not use a background, which I have questions or just curious.
