Expert-Vetted on Upwork (Top 1% of security professionals). If you're building on the cloud and want to find the security gaps attackers would exploit — before they do — I can help. I’m a cybersecurity consultant and founder of Exfiltra, helping startups and enterprises secure their applications, cloud infrastructure, and DevOps pipelines. I have worked with organizations generating $6B+ in annual revenue and helped companies strengthen security across cloud environments, applications, and compliance programs. I personally lead security engagements and, when needed, bring in specialists from my team at Exfiltra to support larger or complex projects. Most clients hire me when they want to: ✔ Secure Azure / AWS / GCP environments ✔ Perform professional penetration testing ✔ Implement DevSecOps and secure CI/CD pipelines ✔ Prepare for SOC 2, ISO 27001, HIPAA, FedRAMP, or CMMC ✔ Improve security posture using industry frameworks CORE EXPERTISE AZURE & CLOUD SECURITY • Azure security architecture reviews • Microsoft Defender for Cloud & Sentinel • Identity security (Entra ID / Conditional Access) • Cloud configuration reviews and CIS Benchmark hardening APPLICATION SECURITY & PENETRATION TESTING • Web application penetration testing • API security testing • Mobile application security testing • Network and cloud penetration testing • Assessments aligned with OWASP Top 10 and OWASP ASVS DEVSECOPS & SECURITY AUTOMATION • Secure CI/CD pipelines (Azure DevOps / GitHub Actions) • Infrastructure as Code security (Terraform / Bicep) • SAST and DAST integration in pipelines SECURITY TOOLS • Snyk • Semgrep • OWASP ZAP • Burp Suite • Wazuh • CrowdStrike • Microsoft Sentinel AI & LLM SECURITY • AI application threat modeling • Prompt injection and model abuse testing • Secure architecture for AI-powered applications WHY CLIENTS WORK WITH ME • Upwork Expert-Vetted (Top 1% of freelancers) • Founder of Exfiltra – a cybersecurity services company • Supported by a team of security specialists for larger engagements • Contributor to OWASP ZAP • Experience securing environments for organizations generating $6B+ in revenue • Background in both software engineering and cybersecurity • Security research involving organizations like the U.S. Department of Defense NOT A GOOD FIT IF • You want to hack or recover social media accounts • You want enterprise-grade security but are not willing to invest in it If your goal is to build secure systems instead of reacting to breaches later, feel free to invite me to your job or send a message describing your project.

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 — 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 · HIPAA · PCI DSS · SOC 2 · 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.
