    Maintenance experience

    I have more than 20 years of experience as a computer technician.

    I was a technician at HM SOFT, the company that held the maintenance contract for more than 300 computers at the Libertador Experimental Pedagogical University (UPEL), “Gervasio Rubio” Rural Pedagogical Institute, in Táchira.

    With Llamen al técnico I handle that kind of work today: checkups, cleaning and tune-ups.

  • Networks and connectivityHome and office networks and internet connections.

    I set up and check the network at your home, office or institution so the connection is stable. Clients work and browse without needless drops.
