xss-labs for learning web application security. Each lab demonstrates a different XSS vulnerability with interactive examples and solutions. Frontend-only, no server required.

I find vulnerabilities in web applications before attackers do. I test web apps, APIs, and mobile apps from an attacker's point of view. I look for flaws like IDOR, XSS, SSRF, CORS issues, access control problems, and other security misconfigurations.
