# Philosophy

> I treat every CTF challenge as a learning opportunity — dissecting source code, bypassing filters, and chaining vulnerabilities into working exploits. This blog is my digital lab notebook: raw, technical, and reproducible.

> When I'm not hunting flags, I'm building offensive tooling, studying protocol internals (HTTP/2, gRPC, WebSockets), or reverse-engineering web frameworks for zero-day research.
