I find the vulnerabilities in your web apps, APIs, and networks before attackers do, then hand your team a clear, reproducible penetration testing report they can act on. GXPN and GCIH certified. Top Rated on Upwork with 100% Job Success across web application, API, and network security engagements. No scanner dump and no jargon wall. Every finding comes with a severity rating (CVSS), working proof of concept, and a concrete fix your developers can ship. What I test: - Web application penetration testing (OWASP Top 10, PTES, NIST) - API security testing (REST, GraphQL, auth/OAuth, IDOR, broken access control) - SaaS and multi-tenant assessments (Supabase / Firebase data-isolation testing) - Network and external perimeter penetration testing - Source code / secure code review How I work: authorized testing only, on systems you own or have permission to test. Everything is documented over Upwork so you get a written record of every finding, not a verbal hand-wave. I retest after you patch to confirm the holes are actually closed. Credentials: GXPN (GIAC Advanced Penetration Tester & Exploit Researcher), GCIH (GIAC Certified Incident Handler), SANS CTF winner, and an active national/international CTF competitor (web, reverse, crypto, forensics). I also handle WordPress malware removal and incident response. See my Project Catalog for a fixed-price option.

Your business has vulnerabilities. The question is whether you find them first or an attacker does. I'm a penetration tester and cloud security specialist with 7 years securing fintech, healthcare, and SaaS environments 50+ cloud infrastructures hardened across AWS, Azure, and GCP, and VAPT engagements spanning web apps, APIs, mobile applications, and Active Directory. I have guided organizations through ISO 27001, HIPAA, PCI DSS, SOC 2, and NIST 800-171 from gap assessment all the way to audit-ready. If you want an ethical hacker who delivers clear, risk-ranked findings your team can actually act on not a scanner report with 300 unfiltered CVEs โ send me a message. Penetration Testing & VAPT I find what automated tools miss. Web applications, mobile apps, APIs, network infrastructure, Active Directory, and cloud platforms all in scope. Manual exploitation, threat modeling, and source code reviews using Burp Suite, Nessus, Metasploit, and custom tooling. Cloud Security & Configuration Hardening A single misconfigured IAM role or exposed storage bucket can compromise your entire infrastructure. I conduct thorough security reviews and implement hardening across AWS, Azure, GCP, and OpenStack covering identity management, network controls, data encryption, zero trust architecture, and container security. Compliance & Regulatory Audits ISO 27001 ยท HIPAA ยท PCI DSS ยท SOC 2 ยท NIST I have supported 3+ ISO 27001 certifications and multiple HIPAA and PCI DSS engagements, focusing on what auditors actually require rather than unnecessary complexity. Ground zero to audit-ready. Red Team & Social Engineering Technology is rarely the weakest link. Adversary simulations, phishing campaigns, physical security assessments, and zero trust evaluation to expose your real-world attack surface beyond the technical perimeter. Digital Forensics & Incident Response (DFIR) When a breach occurs, speed is everything. Breach containment, malware analysis, forensic investigation, threat hunting, SIEM review, and incident response planning so you recover fast and rebuild stronger. My reports are written for decision-makers, not just security teams. I stay involved through remediation, and many clients retain me as an ongoing security advisor. That continued trust is what I consider the strongest measure of the work.
