Hi, I'm Shanmukha(Mr.N0On3), a Security Analyst with a strong interest in identifying real-world vulnerabilities in web applications, APIs, and network environments.

I perform security assessments across Web, API, and Network, and conduct source code reviews to identify logic flaws and security gaps. I also actively participate in CTFs and security research to sharpen my practical skills and stay current with modern attack techniques.

I approach systems from an attacker’s perspective and focus on identifying weaknesses before they can be exploited, helping improve overall security posture.
