Ayushi Singh

I’m a security-focused professional with hands-on experience performing penetration testing and vulnerability assessments, including Nessus-driven scans and internal security testing. In my Penetration Tester (Intern) role, I documented 12+ critical vulnerabilities and collaborated with developers to achieve a 100% remediation rate on high-risk findings.

Beyond testing, I support security improvements in real systems—finding input validation weaknesses in legacy Symfony/Twig components and identifying insecure polling mechanisms that affected data-in-transit security. I also automate reconnaissance and vulnerability scanning with Python and Bash, and I strengthen detection and response by assisting in incident response and log analysis using Splunk and QRadar.

My background also includes security-first software development, where I built a loyalty rewards system using Next.js and .NET Core with JWT authentication and RBAC, and I designed REST APIs with Swagger to reduce authentication errors. I’m CEH certified, a CCEP-certified cybersecurity educator, and I’ve proven performance in CTFs (95th rank among 300+ teams), which fuels my drive to keep learning and delivering measurable security outcomes.
