I help developers and small teams identify real security risks in web applications, not just automated scan results. My focus is understanding how your application actually works, then testing it against realistic attack scenarios: - Broken access control (IDOR, authorization bypass, privilege escalation) - Authentication & authorization issues - Business logic flaws - API security - OWASP Top 10 vulnerabilities through manual testing I start by understanding: ✔ Expected application behavior ✔ User roles and permissions ✔ Critical business flows ✔ Trust boundaries and security assumptions Then I test how those assumptions can break. What you can expect: - Manual testing using Burp Suite and browser developer tools - Evidence-based, reproducible findings - Clear technical explanations developers can understand - Practical remediation guidance - Focus on real impact, not vulnerability count Ideal projects: - Small to mid-size web applications - API security testing - Pre-production security assessments - Access control and business logic validation - Targeted penetration testing My background combines hands-on web/API security testing with professional experience in network and cybersecurity engineering, giving me a broader perspective when assessing application security. If you want someone who thinks like an attacker but communicates like a teammate, let's talk.
