About

I am a Security Engineer specializing in Application Security, VAPT, and secure architecture, backed by 4+ years of hands-on software development experience. With a strong foundation in backend and full-stack development (Node.js, MongoDB, MySQL, AWS), I approach security from an engineering perspective — understanding system design, architecture decisions, and real-world production constraints before assessing risk. My security expertise includes: • Web & API penetration testing aligned with OWASP Top 10 • Identification of IDOR, BOLA, business logic flaws, authentication bypass, and access control weaknesses • Advanced Active Directory and Kerberos exploitation (CRTP) • Red team simulations using Burp Suite, Nmap, Nuclei, SQLMap, and custom automation scripts • Secure code review and API hardening practices Beyond vulnerability discovery, I focus on remediation and long-term security maturity: • Implemented DevSecOps practices with CI/CD security checks and SonarQube integration • Created threat models and security guidelines for development teams • Mentored engineers on secure coding and vulnerability remediation • Led a team of 12+ developers, owning production releases, DevOps pipelines, and database integrity • Acted as primary technical liaison between engineering, QA, and clients during secure deployments My goal is not just to identify weaknesses, but to help organizations build systems that are secure by design — from architecture to deployment. Open to Security Engineering, Application Security, and DevSecOps roles where development and security intersect.
