What I'm looking for

I'm looking for work where I can perform penetration testing, vulnerability assessments, and secure full-stack application development.

At Information Network Security Administration (INSA), I perform penetration testing and vulnerability assessments across internal and external systems. I've tested web applications, APIs, authentication systems, and Android platforms, producing detailed reports with actionable remediation guidance.

I also build and secure full-stack applications using Vue3, Node.js, and TypeScript. My hands-on security work includes red team operations, Keycloak SSO token brute-force testing, ADB exploitation, and Linux and Windows post-exploitation.
