Tooling
I build small tools to understand systems and make repeated work easier.
fadi software engineer / security researcher
I pull systems apart, learn how they work, then build tools that make them better.

What I spend my time on.
Infrastructure
I like tracing what happens between a request and a response: networks, servers, and the things that fail in between.
Automation
If I have to do the same task twice, I usually try to script it.

03 / About
I like knowing how things work.
I’m Fadi. I taught myself to code by taking things apart and trying to put them back together. Now I build tools, study networks, and write about the bugs I find.
