A challenging position as a Technical Manager or Senior Systems Administrator in an environment requiring a diverse array of technical skills.


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.
