During my 6 years experience as a technical specialist I have built networks (LAN) and provided ongoing support services for the Information systems, websites and workstations which are developed by the Companies where I have worked. According to the my professional career grow as a System and Network Administrator my responsibilities are: Installation & administration of Servers such as Microsoft Active Directory, Web Server, Mail Server, Proxy Server, DNS Server, etc.. Development and implementation of data administration policy, standards and models. Working closely with the company's Software Development and Professional service for software defect diagnosis and fixes. As well as I have some experience in the following areas: Database design, development and maintenance.
Over the last 10 years, I'm network administrator, architect and CIO in various hosting and ISP companies. Due this I have relatively good skills in Linux/BSD, virtualization, routing and shell/perl-scripting. My previous professional bio can be divided into 4 independent parts: - from 1990 to 1996 -- system programming for PCDOS (Assembler, C) - from 1996 to 1999 -- HPC programming and teaching for MPI, PVM, HP/Convex - from 1997 to 1998 -- programming for DSP controllers - from 1999 to 2003 -- programming, administration and teaching for Lotus Notes/Domino My current targets are: - programming in C, C++ and Perl - building and managing networks - building and managing virtual environments I prefer opensource whenever it's possible, but without zealotry. I think that the best opensource platform is Linux, but without zealotry too. In my opinion, the best Linux distro is Ubuntu LTS, but without any religious zealotry again.
