Penetration Tester | Web, API & Mobile Security | SOC 2 & ISO 27001

Security isn't just about passing compliance audits—it's about identifying real vulnerabilities before attackers do. I help SaaS companies, fintech startups, healthcare organizations, payment platforms, and enterprise businesses secure their applications through professional penetration testing, vulnerability assessments, application security reviews, and compliance consulting. With 7+ years of cybersecurity experience, I specialize in both offensive security and compliance, allowing businesses to strengthen their security posture while preparing for industry standards like SOC 2, ISO 27001, PCI DSS, and NIST. Unlike consultants who simply deliver vulnerability reports, I provide clear remediation guidance, developer-friendly reports, and practical recommendations that help engineering teams fix security issues efficiently. Whether you're preparing for an external audit, launching a SaaS platform, securing APIs, or validating your application's defenses before production, I help ensure your systems remain secure and compliant. 🔐 𝐖𝐡𝐚𝐭 𝐈 𝐒𝐩𝐞𝐜𝐢𝐚𝐥𝐢𝐳𝐞 𝐈𝐧 𝐖𝐞𝐛 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐏𝐞𝐧𝐞𝐭𝐫𝐚𝐭𝐢𝐨𝐧 𝐓𝐞𝐬𝐭𝐢𝐧𝐠 ✔ Web Application Penetration Testing ✔ OWASP Top 10 Assessment ✔ Authentication & Authorization Testing ✔ Business Logic Testing ✔ Session Management Review ✔ File Upload Security ✔ Cross-Site Scripting (XSS) ✔ SQL Injection Testing ✔ Server-Side Request Forgery (SSRF) ✔ Remote Code Execution (RCE) ✔ Command Injection ✔ Security Misconfiguration Review 𝐀𝐏𝐈 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐓𝐞𝐬𝐭𝐢𝐧𝐠 ✔ REST API Penetration Testing ✔ GraphQL Security Assessment ✔ API Authentication Testing ✔ JWT Security Review ✔ OAuth Security Testing ✔ Rate Limiting Validation ✔ Broken Object Level Authorization (BOLA) ✔ Broken Authentication Testing ✔ API Business Logic Testing ✔ API Vulnerability Assessment ✔ OWASP API Top 10 Testing 𝐌𝐨𝐛𝐢𝐥𝐞 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 ✔ Android Penetration Testing ✔ iOS Security Assessment ✔ OWASP MASVS Testing ✔ Secure Storage Review ✔ Reverse Engineering Assessment ✔ Mobile API Security ✔ Certificate Pinning Validation ✔ Runtime Security Testing ✔ Mobile Authentication Review 𝐕𝐮𝐥𝐧𝐞𝐫𝐚𝐛𝐢𝐥𝐢𝐭𝐲 𝐀𝐬𝐬𝐞𝐬𝐬𝐦𝐞𝐧𝐭 & 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐀𝐮𝐝𝐢𝐭𝐬 ✔ Vulnerability Assessment (VAPT) ✔ Internal Security Assessment ✔ External Network Assessment ✔ Configuration Review ✔ Cloud Security Assessment ✔ Infrastructure Security Review ✔ Risk Assessment ✔ Security Gap Analysis ✔ Security Architecture Review 🛡 𝐂𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐜𝐞 & 𝐆𝐨𝐯𝐞𝐫𝐧𝐚𝐧𝐜𝐞 ✔ SOC 2 Readiness ✔ SOC 2 Type II Preparation ✔ ISO 27001 Implementation ✔ ISMS Development ✔ PCI DSS Compliance ✔ PCI SSF ✔ PCI PIN Security ✔ NIST Cybersecurity Framework ✔ NIST 800-53 ✔ GDPR Security Controls ✔ Security Policy Development ✔ Risk Management ✔ Security Documentation ✔ Internal Audit Support ✔ Compliance Gap Assessment 🔍 𝐀𝐩𝐩𝐥𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐬 ✔ Secure SDLC ✔ Threat Modeling ✔ Secure Code Review ✔ Static Application Security Testing (SAST) ✔ Dynamic Application Security Testing (DAST) ✔ Software Composition Analysis (SCA) ✔ Dependency Vulnerability Analysis ✔ Container Security ✔ CI/CD Security ✔ DevSecOps Implementation ☁ 𝐈𝐧𝐟𝐫𝐚𝐬𝐭𝐫𝐮𝐜𝐭𝐮𝐫𝐞 & 𝐂𝐥𝐨𝐮𝐝 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 ✔ AWS Security Review ✔ Azure Security Assessment ✔ Cloud Configuration Review ✔ Identity & Access Management ✔ Network Security Review ✔ Firewall Rule Assessment ✔ Endpoint Security ✔ Logging & Monitoring 🛠 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐓𝐨𝐨𝐥𝐬 Burp Suite Professional • OWASP ZAP • Nmap • Nessus • Metasploit • Wireshark • Trivy • Dependency-Track • Kali Linux • Postman • MobSF • Ghidra • Docker • Git • GitHub Security • SonarQube 𝐈𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐞𝐬 𝐈 𝐖𝐨𝐫𝐤 𝐖𝐢𝐭𝐡 • FinTech • SaaS • Banking • Payment Platforms • Healthcare • E-commerce • Government • Insurance • Enterprise Software • Cloud Platforms • Startups 𝐖𝐡𝐲 𝐂𝐥𝐢𝐞𝐧𝐭𝐬 𝐖𝐨𝐫𝐤 𝐖𝐢𝐭𝐡 𝐌𝐞 ✔ 7+ Years of Cybersecurity Experience ✔ Offensive Security + Compliance Expertise ✔ Developer-Friendly Reports ✔ Actionable Remediation Guidance ✔ Secure SDLC Knowledge ✔ Strong Understanding of Modern Web Technologies ✔ Fast Communication ✔ Confidential & Professional Engagements ✔ Long-Term Security Partnership I don't deliver generic vulnerability scans.
