⭐️⭐️⭐️⭐️⭐️ I don't just find vulnerabilities - I prove how attackers can exploit them, help you fix them, and verify they're gone.
12+ years | 663+ clients | 900+ security assessments | 2,700+ vulnerabilities identified
I'm a Cybersecurity Engineer, Penetration Tester, Cloud Security Engineer, and Ethical Hacker with 12+ years of hands-on experience. I've worked with 663+ clients across 36 countries, completed 900+ security assessments, identified 2,700+ vulnerabilities, and built an 80% repeat-client rate by focusing on practical security outcomes—not generic scanner reports.
Whether you need a Cybersecurity Engineer to strengthen your infrastructure, a Penetration Tester for an upcoming assessment, a Cloud Security Engineer to secure AWS, Azure, or GCP, or an experienced Ethical Hacker to simulate real-world attacks, I provide clear findings, verified exploitation, and actionable remediation.
🛡️ Why Clients Choose Me
• 12+ years of professional Cyber Security experience

As a Cybersecurity Expert, I've helped startups and enterprises across FinTech, Healthcare, SaaS, eCommerce, Blockchain, and Government improve their Cyber Security, strengthen Cloud Security, and prepare for SOC 2, HIPAA, ISO 27001, and PCI DSS.
🔐 Core Security Services
Web Application Penetration Testing
As a Penetration Tester, I combine manual exploitation with targeted automation to identify vulnerabilities scanners frequently miss:
SQL Injection • XSS • SSRF • XXE • CSRF • RCE • IDOR • Authentication & Authorization flaws • Business Logic vulnerabilities • Race Conditions • API Security • OWASP Top 10
I don't simply report that a vulnerability exists—I demonstrate its real-world impact with reproducible PoCs.
☁️ Cloud Security — AWS | Azure | GCP
As a Cloud Security Engineer, I assess and harden cloud environments across:
IAM • Kubernetes • Docker • S3/Cloud Storage • VPC • Serverless • CI/CD • Infrastructure as Code • Secrets Management • Logging & Monitoring • DevSecOps
My Cloud Security assessments focus on real attack paths, including privilege escalation, excessive permissions, exposed assets, insecure IAM policies, vulnerable Kubernetes configurations, and cloud misconfigurations.
🌐 Infrastructure & Mobile Security
Infrastructure penetration testing covering Windows, Linux, Active Directory, VPNs, firewalls, wireless networks, privilege escalation, lateral movement, and network segmentation.
Mobile application security for Android and iOS, including reverse engineering, static/dynamic analysis, API security, secure storage, certificate pinning, root detection, and jailbreak detection.
As a Cybersecurity Engineer, I approach every environment from an attacker's perspective while keeping remediation practical for your engineering team.
💻 Secure Code Review & Incident Response
Manual code review, SAST, DAST, malware analysis, digital forensics, threat hunting, cloud forensics, and Incident Response.
I also work closely with Java Developer teams, DevOps engineers, architects, security teams, and IT Project Manager stakeholders to integrate security into development and improve overall IT Service reliability.
