About

Security tinkerer, community builder, and someone who learns by taking things apart.

I'm Conan, conanzhangtech pretty much everywhere online. I'm from Singapore, and I understand things best by building them, breaking them (safely) and putting them back together.

Most of what I do sits between cybersecurity and community. I play CTFs, I run a home lab where ideas get tested before they go anywhere real, and I co-founded Isolated Command, a youth community where young people get hands-on with security and tech instead of just reading about it.

Helping people who are just starting out has been part of my journey from the start, and it's still the part I enjoy most.
