Where there is code, there is a vulnerability waiting to be found. > I am a Cybersecurity Researcher and Bug Hunter. Between my full-time tech career, my academic studies as an engineer , and competing in Capture The Flag (CTF) events, I live and breathe offensive security. Now, I'm taking that hacker mindset and giving back to the community by helping developers secure their applications. Are you completely sure your web app is safe from modern threats? I am currently open for collaboration. What I bring to the table: Deep-dive vulnerability assessments and bug hunting for your web applications. Comprehensive, easy-to-understand vulnerability reports. Actionable strategies to harden your web app against real-world attacks. Let's find your vulnerabilities before the bad guys do. Send me a message to get started.
