Most businesses discover security vulnerabilities the hard way—after a breach, data leak, or compliance failure that costs them customers, reputation, and revenue. I help you avoid that nightmare by identifying and fixing security weaknesses before they become headlines. I'm an Application Security Engineer who has worked for 2 Fortune 500 Companies, with hands-on expertise in web, mobile, and thick-client application security. Armed with industry-recognised certifications including Burp Suite Certified Practitioner (BSCP), Certified Ethical Hacker (CEH), and Certified Penetration Testing Specialist, I don't just run automated scans—I think like an attacker to uncover the vulnerabilities that tools miss. 🎯 What Makes Me Different Client-Focused Security: I don't overwhelm you with jargon. You'll get clear explanations of what's broken, why it matters to your business, and exactly how to fix it. Beyond Checkbox Security: Automated scanners catch maybe 30% of real vulnerabilities. I perform deep manual testing that combines technical expertise with creative thinking to find logic flaws, business logic vulnerabilities, and complex attack chains. You're Not Left Hanging: Every engagement includes remediation guidance and a free retest to verify your fixes actually work—because closing a ticket isn't the same as closing a vulnerability. 🔒 Services I Provide: Penetration Testing & Security Assessments - Web application penetration testing (OWASP Top 10 and beyond) - Mobile application security testing (Android & iOS) - Thick client application assessment - API security testing - Both manual and automated testing methodologies Source Code Security Review - Static code analysis to identify security flaws at the source - Secure code review before deployment - Identification of insecure coding patterns and logic vulnerabilities Vulnerability Assessment & Management - Comprehensive vulnerability scanning and analysis - Risk prioritization based on real business impact - Actionable remediation roadmaps Security Audits & Compliance Support - Security posture assessments - Pre-compliance security reviews - Gap analysis and security hardening recommendations 📋 What You'll Receive: ✅ Professional Penetration Testing Report – Detailed findings with step-by-step exploitation methods, CVSS scores, business impact analysis, and proof-of-concept evidence ✅ Clear Remediation Guidance – Specific, actionable fix recommendations your developers can implement immediately (no vague advice like "improve security") ✅ Executive Summary – Non-technical overview for stakeholders showing what matters to the business, not just what's technically interesting ✅ Free Vulnerability Retest – I verify your fixes actually solved the problem and didn't introduce new issues ✅ Pre & Post Engagement Calls – We'll discuss scope, methodology, testing windows, and any concerns before starting. After testing, I'll walk you through findings and answer all questions 🛡️ My Approach: Before Testing: I work with you to understand your business context, critical assets, and main concerns. A banking app and a social media platform have different threat models—your security testing should reflect that. During Testing: I combine automated tools (Burp Suite Professional, industry-standard scanners) with manual testing techniques to find vulnerabilities that require human intuition and creativity. After Testing: You don't just get a report and a goodbye. I'm available to clarify findings, guide your remediation efforts, and retest to confirm everything is actually fixed. 💡 Common Problems I Solve: "We're launching soon and need to know if our application is secure" "We failed a compliance audit and need to identify and fix security gaps" "Our previous security test was full of false positives and didn't help us" "We need to prove to clients/investors that our product is secure" "Our application handles sensitive data and we can't afford a breach" "We've been hacked before and need to prevent it from happening again" 🎖️ Certifications: Burp Suite Certified Practitioner (BSCP) Certified Ethical Hacker (CEH) Certified Penetration Testing Specialist Your application's security shouldn't be a gamble. Let's work together to identify your vulnerabilities before someone with bad intentions does. Ready to secure your application?
