About

I’m an early-career cybersecurity analyst focused on web application security, penetration testing, and AI security. I work with tools and workflows like Burp Suite, Nmap, Nessus, Wireshark, and Kali Linux to assess attack surfaces, validate findings, and produce security feedback that’s grounded in real testing evidence.

I also help evaluate AI-assisted vulnerability results by manually checking reports for false positives and missed issues, so the final risk assessment reflects what actually happens in practice. I’m currently building deeper expertise through authorized freelance engagements, security projects, and lab work while working toward the CompTIA PenTest+ certification.
