I'm a cybersecurity professional with 5+ years of hands-on penetration testing experience, helping businesses identify and eliminate critical vulnerabilities before attackers do. I specialize in web application penetration testing, API testing, network security, and cloud security, delivering clear, actionable reports that your team can actually use. As a veteran bug bounty hunter, I've reported vulnerabilities across 100+ programs, including Apple (BeatsByDre), Dropbox, Steam, eBay, Opera, VMware, and H&M, covering XSS, SQLi, SSRF, CSRF, XXE, RCE, S3 misconfigurations, subdomain takeovers, and more. Real-world attack experience, not just theory. 🏆 Winner of REDACTED 2025 Hackathon for research on Web2 vulnerabilities in emerging technology environments. 🧰 Core Services: 1. Web App Penetration Testing: OWASP Top 10, authentication & session flaws, access control, IDOR, SSRF, business logic vulnerabilities 2. API Security Testing: REST & GraphQL authorization, token/session handling, input fuzzing, business logic abuse 3. Network Security & Red Team Assessments: Internal/external network testing, segmentation validation, attack path simulation 4. Cloud Security: AWS/Azure misconfigurations, IAM privilege analysis, exposure discovery (Cloud Security) 5. Microsoft Active Directory: Enumeration, privilege escalation paths, and lateral movement simulation 6. Vulnerability Assessment & Risk Assessment: Prioritized findings mapped to real-world business impact 7. Compliance-Aligned Testing: HIPAA, GDPR, NIST SP 800-53, security assessments tailored to your regulatory requirements 8. User Identity Management: SSO, OAuth, MFA, session management, and access control testing 9. AI Security & Blockchain Security: Emerging attack surfaces including AI-powered applications and Web3/Web2 hybrid systems ✅ What You Get: - Manual testing, not just automated Nessus or scanner output - Findings prioritized by real-world exploitability, not CVSS scores alone - Executive summary + developer-friendly remediation steps your team can act on immediately - Black box, grey box, and white box engagements available - Fast, clear communication throughout, no surprises - Full confidentiality and NDA available on request 🔐 Why Clients Choose Me: With a background spanning traditional penetration testing, active bug bounty hunting, and enterprise security assessments, I bring attacker-level thinking to every engagement. I don't just run tools; I think like an adversary, chain vulnerabilities, and surface the issues that matter most to your business.
