Job Success
Karachi, Pakistan - 10:00 pm local time
With 7+ years of experience in penetration testing and offensive security, I specialize in assessing web applications, APIs, mobile applications, and cloud environments and delivering clear, developer-friendly remediation guidance.
My goal is simple: find the vulnerabilities that matter, explain the real business risk, and help your development team fix them properly.
🔐 PENETRATION TESTING SERVICES
• Web Application Penetration Testing
• API Security Testing
• Mobile Application Security Testing
• Cloud Security Assessments
• Vulnerability Assessment
• OWASP Top 10 Security Testing
• Authentication & Authorization Testing
• Business Logic Testing
• Security Misconfiguration Testing
• Manual Vulnerability Verification
• Security Retesting & Remediation Validation
🛡️ WEB APPLICATION SECURITY
I test web applications for vulnerabilities including:
• SQL Injection
• Cross-Site Scripting (XSS)
• CSRF
• SSRF
• Broken Access Control
• IDOR
• Authentication weaknesses
• Session management issues
• File upload vulnerabilities
• Security misconfigurations
• Business logic flaws
• Sensitive data exposure
🔌 API SECURITY
Security testing for REST, GraphQL, and other API-based applications, including:
• Broken Object Level Authorization
• Authentication vulnerabilities
• Authorization flaws
• Excessive data exposure
• Injection vulnerabilities
• Rate-limit issues
• API misconfigurations
• Token and session security
• Business logic vulnerabilities
📱 MOBILE APPLICATION SECURITY
Security assessment of iOS and Android applications covering:
• Insecure local storage
• Weak authentication
• API exposure
• Sensitive data leakage
• Application configuration issues
• Reverse engineering risks
• Client-side security weaknesses
☁️ CLOUD SECURITY
Security reviews for cloud environments including AWS, Azure, and GCP, focusing on:
• Access control
• IAM configuration
• Publicly exposed services
• Storage permissions
• Secrets and credentials
• Security groups
• Misconfigurations
• Excessive privileges
📄 WHAT YOU RECEIVE
Every assessment includes clear documentation designed for both technical and non-technical stakeholders.
You receive:
✓ Executive security summary
✓ Verified vulnerability findings
✓ Severity and risk prioritization
✓ Reproduction steps
✓ Evidence and technical details
✓ Business impact explanation
✓ Developer-friendly remediation guidance
✓ Retesting support when required
I prioritize manual security testing rather than relying entirely on automated vulnerability scanners. Automated tools can assist discovery, but vulnerabilities are manually validated to reduce false positives and identify logic flaws automated scanners frequently miss.
🏆 EXPERIENCE
• 7+ years in penetration testing and application security
• Security assessments across web, API, mobile, and cloud environments
• Experience working with development and Agile teams
• Developer-friendly vulnerability reporting and remediation support
• Security testing for applications handling sensitive business and customer data
📜 CERTIFICATIONS
• OSCP – Offensive Security Certified Professional
• CEH – Certified Ethical Hacker
• CompTIA Security+
WHY WORK WITH ME?
✓ Manual-first penetration testing
✓ Clear and actionable security reports
✓ Business-risk-focused vulnerability prioritization
✓ Confidential handling of sensitive information
✓ Clear communication throughout the assessment
✓ Practical remediation guidance for developers
✓ Retesting support after fixes
Security testing should do more than generate a long vulnerability report. It should help you understand what can actually be exploited, what needs to be fixed first, and how to reduce your real security risk.
If you need a penetration test, security assessment, vulnerability review, or independent security validation before launch, send me your project details and I’ll recommend the appropriate testing approach.
