I am a licensed Amateur Radio Operator with the callsign VE4FEB. My main
focus is on RF projects, and I occasionally check in on radio nets on the 2m
band. I am also active in CW mode, primarily on the 40m, 20m, and 15m bands.
Special thanks to Adam VE4SN for coming to my house to administer my exam.
I have over 20 years of professional experience in Electronics Engineering,
specializing in design, debugging, and manufacturing support. I spent eight
years in the Philippines working on power electronics product development
before taking on system-level hardware development roles in Hong Kong and
Malaysia.
In the late 1990s, I dedicated much of my time to studying self-replicating
programs, focusing on infection and stealth techniques. My primary interests
included polymorphism, encryption, multipartite, and multiplatform
techniques. During this period, I learned 32-bit Windows and extended DOS
assembly programming. My first Unix experience was with an AT&T System V
(SVR2)-compatible version of D-Nix running on a Motorola 68k while
performing field maintenance for a bank’s client management system. I fully
transitioned to Linux when Red Hat 6.1 was released, later switching between
Slackware, Debian, and LFS 3.3, before settling on Crux. Around 2006, I
switched to OpenBSD.
