Objective

A challenging position as a Technical Manager or Senior Systems Administrator in an

environment requiring a diverse array of technical skills.

Summary

I've been working with computers since 1984. As a curious and

open minded person, I'm naturally drawn to positions requiring a

substantial knowledge and involvement with computers. My assignments

so far included system and BIOS level programming, Systems

Administration (HP-UX, Unix and Linux), network, and database

administration (Oracle). My current position, as a Technical

Manager for NDS Americas (a News Corp company), allows me to employ all these skills to

solve complex problems in a realtime digital TV broadcasting and

access-control system for Sky Latin America.

I have over 8 years of experience in Unix/Linux

administration (HP-UX, SCO, ISC Unix and various flavours of Linux), as well

as networking (TCP/IP, Cisco Routers, Switches and firewalls). I am very

comfortable with Unix in general, and in particular with the Linux operating

system, which I've been using as my desktop operating system for the last six years.

I'm also conversant with most technologies and protocols that make up

the Internet, having offered consultancy services to Internet Service

Providers between 1996 and 1999. At that time, I helped design,

install, configure, secure, and manage most aspects of various ISPs, including

Web Servers, Mail Servers, News Servers, DNS, Routers, Terminal Servers and

Firewalls.

I'm proficient in many programming and markup languages, including C, ASMx86,

Shell Scripting, Perl 5, Python and HTML. I authored two open source projects: "Angel",

a simplistic Network Monitor written in Perl and "ASK", a challenge-response

anti-spam solution written in Python, for which I wrote a paper published in the

FREENIX track of the 2003 Annual Usenix Conference.
