Security Researcher (Authentication & Access Control)
Freelance Security Research • Freelance

I specialize in analyzing authentication and authorization logic in modern web applications and SaaS platforms. My work focuses on: - Testing login and logout flows (SSO, OAuth, OIDC) - Identifying logic flaws in authentication and access control - Validating redirect handling and session management - Reviewing identity configurations for security and robustness I perform manual security testing in controlled and isolated environments, focusing on real-world attack scenarios such as authentication bypass, misconfigured redirects, and logic gaps rather than generic automated scans. All testing is conducted responsibly, with clear documentation and actionable security findings.
