What I'm looking for

I seek roles focused on offensive security, DevSecOps integration, and AI-enhanced vulnerability discovery within collaborative teams that value automation, mentorship, and measurable security outcomes.

I am a Senior Technical Lead and security engineer with 8+ years of hands-on experience in penetration testing, vulnerability assessment, and DevSecOps. I have executed hundreds of web, API, mobile, and network security assessments to identify and remediate critical vulnerabilities.

I have a strong track record in bug bounty programs and community leadership, validated by 500+ vulnerability disclosures, a Bugcrowd Top 150 ranking, Hall of Fame recognitions, and authorship of CVE-2024-20928. I have also earned high rankings and payouts on HackerOne.

My technical skillset spans SAST/DAST tools, network and embedded device testing, scripting, and building security test labs. I spearheaded DevSecOps initiatives, integrating security tools into CI/CD pipelines and creating an in-house cloud configuration audit tool to automate compliance and streamline vulnerability management.

I apply AI-driven techniques to accelerate vulnerability discovery and pioneered AI security applications in healthcare devices. I mentor researchers, promote testing automation, and focus on practical, scalable security solutions that help organizations defend against evolving cyber threats.
