I’m a cybersecurity enthusiast and dedicated specialist focused on black-box penetration testing for web applications and APIs. I use both manual and automated techniques to uncover and exploit security vulnerabilities, with strong grounding in web technologies, HTTP protocols, authentication mechanisms, and API security.

In my current cybersecurity internship, I independently perform vulnerability assessments and penetration testing on web and Android applications. I follow OWASP Top 10 and ISO 27001 standards, conduct active testing with tools like Burp Suite, OWASP ZAP, Nmap, and SQLmap, and document findings with risk impact and remediation recommendations.

I’ve supported authorized VAPT work for a government client and completed web VAPT for Harman Audio’s website, translating technical issues for both technical and non-technical stakeholders. I also work closely with development and infrastructure teams to enhance security measures and reduce risk exposure.

I’m actively working toward CEH certification and building breadth across SOC monitoring, incident response fundamentals, network security, and cryptography. My approach is detail-oriented and proactive—staying ahead of evolving threats and security best practices while improving defensive outcomes.
