Manual Android App & API Security Tester focused on finding real vulnerabilities.

I am an independent Android application and API security tester with a
focus on manual testing and practical vulnerability assessment.

I work with native Android applications (Java/Kotlin) and backend APIs
to help developers understand whether their app is secure or vulnerable
before release. My approach is hands-on and detail-oriented, using
simple and effective testing techniques to identify real security
weaknesses rather than relying heavily on automated tools.

My work typically includes reviewing authentication and authorization
logic, insecure data handling, exposed API endpoints, and common issues
aligned with the OWASP Mobile Top 10. I believe in clear communication
and transparent reporting, so clients always understand the impact of
any issues found.

I value ethical testing, defined scope, and client permission. My goal
is to provide useful, actionable feedback that helps improve app
security and build safer mobile products.
