I help SaaS companies, and enterprises identify critical security vulnerabilities before they become costly breaches, compliance issues, or business disruptions. As an Application Security Consultant and Penetration Tester, I specialize in uncovering real-world security weaknesses across web applications, APIs, network infrastructure, cloud environments, and modern technology platforms. My goal is not only to identify vulnerabilities but also to help organizations understand their security risks, prioritize remediation efforts, and strengthen their overall security posture. I have worked on security assessments involving enterprise applications, banking platforms, healthcare systems, cloud infrastructures, and business-critical applications. My experience includes identifying authentication flaws, access control weaknesses, business logic vulnerabilities, network misconfigurations, cloud security gaps, API security issues, and attack paths that automated scanners frequently miss.

If any of those is you, you're in the right place.

Whether it's a regulator, an auditor, an investor, or an enterprise customer asking the hard questions, send me the scope and I'll tell you straight where you stand and what I'd fix first.
