Hi, I’m Lee

I’m an IT Security Officer based in Manila. I began my security journey as a Threat Response Engineer, analyzing Windows and macOS binaries down to the bits and bytes. Over time, I moved into Incident Response, taking on projects involving automation and asset management. I now dedicate my time to Detection Engineering where I help my organization improve its detection and response capabilities against the ever evolving threat landscape.

I created this site to maintain a personal technical blog and share security topics that I find particularly interesting. Be sure to check out my latest post here .

Outside of cybersecurity, I'm an avid reader, fitness enthusiast, novice photographer and InfoSec student.
