Experienced penetration tester and red team specialist, delivering VAPT, adversary emulation, and AI-focused security assessments.
What I'm looking for
I’m an experienced Penetration Tester and Red Team professional specializing in vulnerability assessment and penetration testing across web applications, APIs, network infrastructure, and cloud infrastructure, including Active Directory domain penetration testing. I combine adversary emulation and exploit development to uncover critical vulnerabilities and simulate real-world attack scenarios, including mobile platforms.
In my recent roles, I’ve conducted internal and external VAPT for zero-trust web application solutions and cloud security products while partnering with product engineering to integrate security best practices across the development lifecycle. I also collaborate with Security Operations Center teams by running red team exercises with defensive monitoring (blue teaming), delivering actionable VAPT reporting and remediation guidance, and executing specialized red teaming for AI-driven product functionalities (LLM testing, phishing activities, and privilege escalation techniques).
