About
Cybersecurity & IT Professional based in North York, Ontario, Canada.
I'm Taki Sadik — a cybersecurity and IT professional who likes to own his stack end-to-end. My day job involves triaging security alerts and analyzing threats at a SOC. Outside of work, I run a homelab with Proxmox, self-host services ranging from a private AI model to a public Wikipedia mirror, and document everything I learn through hands-on labs.
I got into IT through surveillance operations and discovered I cared more about the network underneath the cameras than the footage they captured. That curiosity led me to networking, then Linux administration, then cloud, then security. Currently pursuing CompTIA Security+, A+, and CCNA.
