# Whoami

I’m **ShadowSensei**, a **PJPT-certified penetration tester** focused on offensive security, vulnerability assessment, and red-team operations.

I enjoy breaking systems to understand how they can be secured—working across **network, web, API, Linux, and Active Directory security** through hands-on labs, security projects, and real-world learning.

Currently, I’m focused on strengthening my skills in **penetration testing, Active Directory, web/API security, and red-team methodologies** while building practical security tools and documenting my work.

### What’s Inside Here?

This is my practical offensive-security portfolio — **hands-on work, methodology, and lessons learned.**
