What I'm looking for

I seek hands-on offensive security roles where I can perform VAPT, red team operations, and exploit development while collaborating with teams to harden applications and cloud environments.

I am a penetration tester with deep practical experience performing end-to-end VAPT across web, mobile, API, and backend systems. I apply manual exploitation techniques and industry tools to identify and validate vulnerabilities.

I hold multiple Offensive Security certifications (OSCP, OSWE, OSED) and CRTE, reflecting my expertise in exploit development, web application testing, and red team techniques. I stay current through labs, conferences, and continuous research.

In client engagements I deliver technical reports, proofs-of-concept, risk ratings, and executive summaries tailored to diverse stakeholders. I have conducted internal network assessments, AD enumeration, privilege escalation, lateral movement, and post-exploitation analysis.

I collaborate with cross-functional teams and external vendors to harden networks, cloud workloads, APIs, and critical infrastructure, while emphasizing manual validation over purely tool-driven assessments.
