Who I Am

I'm a Senior Application Security Engineer specializing in web application penetration testing, iOS/Android mobile security, API assessments, and source code analysis (SCA). With over 5 years across banking, e-commerce, and enterprise environments, I bridge the gap between offensive security findings and practical remediation.

Currently a Senior Associate at PwC, I build internal security automation tools alongside conducting comprehensive assessments. Previously at Black Duck (Synopsys), I led teams, mentored junior consultants, and delivered executive-level security roadmaps to C-suite stakeholders.

My proudest achievement: discovering and responsibly disclosing 3 CVEs — CVE-2024-35581, CVE-2024-35582, CVE-2024-35583 — now published in the MITRE and NVD databases.
