What I'm looking for

I'm looking to strengthen secure-by-design practices through application and API security, DevSecOps automation, threat modeling, penetration testing, and collaborative vulnerability remediation.

I've led application security for web applications and APIs at NCORE Technology, integrating SAST and DAST into CI/CD workflows and driving remediation with Engineering, QA, and DevOps teams.

I perform threat modeling with STRIDE, validate findings to eliminate false positives, prioritize risks using CVSS, and test API vulnerabilities including BOLA, authentication, authorization, and rate-limiting weaknesses. My work contributed to a reported 50% reduction in late-stage vulnerabilities and a 25% improvement in remediation speed.

Previously at SVR Enterprises, I delivered end-to-end web, API, and network penetration tests for international clients, producing actionable reports, revalidating fixes, and helping developers understand business impact and secure coding practices.
