About Me
I'm a security researcher and developer focused on creating tools & resources that help others learn and grow in cybersecurity and AI development.
My work spans penetration testing methodologies, CTF competition resources, and AI development guides. I believe in making knowledge accessible and open-source.
When I'm not coding, you'll find me participating in CTF competitions, hunting bugs, exploring new AI models, or contributing to the security community.
