Who I Am

I am a results-driven Red Team Researcher with 6+ years of experience specializing in deep penetration testing and offensive security assessments. My expertise spans across web applications, mobile platforms, APIs, Active Directory environments, and the cutting-edge attack vectors of AI/LLM systems.

I specialize in executing realistic APT simulations, bypassing advanced EDR and antivirus systems, and developing custom offensive tools to systematically challenge defense postures. My security research has been recognized by over 100 industry-leading organizations—including Microsoft, Apple, NASA, and the U.S. Department of Defense—and has resulted in 5 published CVEs.

In addition to active operational assessments, I am highly committed to the global cybersecurity community. I serve on advisory boards, organize industry events, speak at tech conferences, and author custom CTF challenges to help train the next generation of cybersecurity talent.
