What I'm looking for

I seek senior application security roles where I can lead vulnerability assessments, integrate DevSecOps tooling, and collaborate with engineering to harden web, API, and mobile products while improving compliance and reducing risk.

I am an application security engineer with 5+ years of experience securing web, API, and mobile platforms through vulnerability assessment, penetration testing, and reverse engineering. I focus on integrating security into development workflows and translating technical risks into actionable improvements.

In recent roles I conducted 30+ comprehensive security assessments and internal audits, driving a 60% decrease in exploitable threat vectors. I led security evaluations of 4+ core products, remediated OWASP Top 10 issues, and contributed to a 75% improvement in application security posture with zero data breaches during assessments.

I spearheaded a Mobile Device Management rollout across 500+ endpoints, enforcing baselines and DLP to achieve a 90% reduction in mobile-related incidents. I routinely perform static and dynamic reverse engineering of Android apps and map findings to OWASP MASVS and API Top 10 standards to eliminate high-impact risks before production.

I bring hands-on experience with DevSecOps practices—integrating SAST, DAST, and SCA tools, running threat modeling (STRIDE) in the SDLC, and partnering with engineering and DevOps to validate fixes. I hold practical certifications and continually pursue advanced training to keep security practices current and practical for product teams.
