I get brought in before it does. I work with companies that take their security posture seriously, whether that means building out a SOC function from scratch, running structured penetration tests against production environments, or walking a business through the full PCI DSS compliance lifecycle as a Qualified Security Assessor. My work sits at the intersection of offensive and defensive security. On the offensive side, I conduct web application, network, and infrastructure penetration tests using methodologies aligned with OWASP, PTES, and NIST. On the defensive side, I build and tune SOC workflows, threat detection pipelines, SIEM configurations, and incident response playbooks that actually get used. For clients in fintech, e-commerce, and SaaS, PCI compliance is often the most high-stakes engagement. I handle scoping, gap assessments, control implementation, and QSA reporting without the consultant-speak that most firms hide behind. A few things that stay consistent across every engagement: I document everything, I communicate findings in plain language to both technical and non-technical stakeholders, and I do not disappear after delivery. If you are dealing with an audit, a breach, a compliance deadline, or just a security program that needs a second set of expert eyes, let's talk. - $53/hr$53 hourly

Vulnerability AssessmentInformation SecurityNetwork SecuritySecurity AnalysisSecurity TestingI help e-commerce businesses identify visible security risks through external, manual and non-intrusive security audits. I work with online stores built on WordPress/WooCommerce, PrestaShop, Shopify, Magento and other e-commerce platforms. My audits are designed to give store owners, agencies and business teams a clear, independent and actionable view of their website’s external security posture. The assessment focuses on publicly observable risks: exposed CMS or e-commerce components, weak security headers, HTTPS and browser trust issues, login and account area exposure, public API exposure, third-party scripts on sensitive pages, checkout-related security signals, domain/email indicators and visible misconfigurations. You will receive a concise report explaining: - what was observed - why it matters - the possible business impact - the priority level - what your developer or technical provider should fix first I am OSCP certified and have practical experience in offensive security, web application testing and vulnerability assessment. I do not sell website maintenance or remediation services. My role is to provide an independent assessment and a clear roadmap for your technical team. This service is especially useful before a campaign, after a redesign or migration, before a cyber insurance request, or when you need an independent view of your e-commerce security posture. - $105/hr$105 hourly

I find the vulnerabilities they miss. I’m a senior penetration tester and vulnerability researcher with deep experience across enterprise networks, web apps / APIs and cloud platforms. Most testers just run automated tools and hand you a generic report. I simulate how an attacker actually thinks, perform thorough testing, and deliver professional, tailored reporting suitable not just for your own remediation efforts but also for audit / compliance. Benefits of manual testing: - Chaining multiple low/medium findings to show more significant impact - Breaking multi-tenant isolation - Bypassing auth controls (JWT, OAuth, misconfigurations) - Identifying cost-amplification / abuse vectors (e.g., billing attacks in serverless environments) - ZERO false positives (and wasted time trying to remediate non-issues) - REAL severity scoring (not just CVSS or ratings with no connection to actual impact/risk for your systems and data) What I Deliver - Manual, attacker-style testing (not just scans) - Clear, prioritized findings with real business impact - Proof-of-concept exploits where it matters - Practical remediation guidance your devs can use immediately - Optional retesting to verify fixes Common Engagements - SaaS / multi-tenant application security testing - API and authentication testing (JWT, OAuth, session flaws) - Cloud security reviews (GCP, AWS, Azure, O365) - DevOps security reviews (Gitlab/hub, BitBucket, etc.) - Pre-SOC2 / investor readiness assessments - High-intensity black-box pentests Why Clients Hire Me - I go beyond the scan—I find what others miss - I understand both offense and architecture - I communicate clearly with both engineers and leadership - I’ve worked on MANY real-world, high-impact systems I also help organizations: - Investigate breaches - Contain active threats - Recover compromised systems (Note: I do not assist with social media account recovery.) - $60/hr$60 hourly
