What I'm looking for

I'm seeking a cybersecurity internship where I can apply penetration testing skills in real-world security environments.

I've built Authenticatingxyz, an end-to-end JWT authentication system using FastAPI, PyJWT, PostgreSQL, Supabase, and Render. I implemented secure registration, login, token refresh, protected routes, bcrypt hashing, rate limiting, HTTPOnly cookies, and a responsive JavaScript frontend.

Through vulnerable web application labs, I set up OWASP applications and DVWA with Docker and performed simulated privilege escalation, command injection, authentication-flaw, SQL injection, and CSRF attacks. I use Burp Suite, Nmap, Subfinder, OWASP ZAP, and Wireshark to analyze traffic, develop proof-of-concepts, and document mitigation-focused technical reports.

I've solved challenges on picoCTF, Hack The Box, PortSwigger Web Security Academy, and international CTFs. As Cyber Security Lead at Google Developer Groups on Campus, I hosted CTF events, increased student participation by 30%, and delivered cybersecurity bootcamps.
