Penetration Tester | Web, Mobile & API Security Specialist | Ethical Hacker Automated vulnerability scanners produce noise; real attackers look for logical flaws. I help businesses, SaaS founders, and development teams identify and patch critical vulnerabilities before malicious actors find them. As an active cybersecurity researcher and penetration tester, I specialize in deep manual assessment across Web Applications, Mobile Apps (Android & iOS), and APIs (REST & GraphQL). Whether you are prepping for a production release, fulfilling third-party security requirements, or securing sensitive user data, I deliver actionable findings that developers can fix immediately. Core Services Web Application Penetration Testing: Thorough testing for OWASP Top 10 vulnerabilities, business logic flaws, race conditions, authentication/authorization bypasses, and account takeovers. API Security Audits: Deep manual testing of REST, SOAP, and GraphQL endpoints focusing on BOLA/IDOR, broken object-level authorization, mass assignment, and improper rate limiting. Mobile App Security (iOS & Android): Static (SAST) and dynamic (DAST) analysis, reverse engineering, insecure local storage, bypasses for root/jailbreak and SSL pinning, and sensitive data leakage. Vulnerability Assessment & Risk Analysis: Surface mapping, configuration reviews, and risk scoring using the industry-standard CVSS framework. What You Receive in the Deliverables You won’t receive an unedited raw scanner output. You get an enterprise-grade, developer-friendly audit report containing: Executive Summary: Plain-English risk overview and business impact analysis for non-technical stakeholders and management. CVSS-Rated Vulnerability Breakdown: Clear severity classifications (Critical, High, Medium, Low, Informational). Step-by-Step Proof of Concept (PoC): Fully reproducible steps, screenshots, request/response dumps, or exploit scripts so your team can confirm the issue instantly. Actionable Remediation Guidance: Concrete code-level or configuration recommendations to resolve the flaw. Free Re-Testing: Verification testing on patched vulnerabilities to ensure they are completely closed before closing the project. How We Work Together Scope Definition: We clarify target domains, test environments, API documentation, and staging credentials. Execution: In-depth black-box, grey-box, or white-box security testing within agreed rules of engagement. Delivery & Support: I provide the initial report and walk your developers through any complex findings. Need your application audited?
