About me

With extensive hands on experience and excellent troubleshooting skills in Systems Administration acquired during the last 16 years, I have been part of varied types of companies and institutions, learned about different systems infrastructures, their problems and how to cope with them.

The last five years I have worked at the Central Bank of Argentine Republic in Systems Administration (IT Datacenter’s Support), which among its main responsibilities is the Acquisition, Commissioning, Management and Support of the Bank’s physical and virtual infrastructure.

The Finance and Banking challenging environment allowed me to work in many projects with different equipment technologies (Blade servers, SANs), remote contingency sites, clustered tape backup infrastructure, monitoring software (Nagios), virtualization (VMWare) and Operating Systems (Windows / Linux).

I see myself as a hard working person, detail oriented, adaptable, confident facing problems, resourceful and always looking for challenges. Recently I have moved in to Doha (Qatar) to start a new stage of my professional career.
