Network & System Administration
To stay abreast with technologies related to Internet Protocol (IP), Network
Technology and System Administration.
Unix/Windows systems and network administration are my primary interests. I
have extensive experience with multiple UNIX-based / windows operating systems with an emphasis on Linux, FreeBSD and Solaris, Cisco networking hardware, system and network security, network design and unix backups. I use Perl / UNIX shell scripts on a regular basis for system administration tasks and am familiar with some C/C++, PHP, VB programming.
While working for an Internet Service Provider, I have installed, configured
and maintained various Open source software and services on Unix Platform to
provide essential services such as DNS, Mail, Proxy, Web, Database, Radius
I learn new concepts and systems quickly and am receptive to new ideas. I work
well alone or in a group and also have self-learning capability.
