6+ years as a Security Researcher, CEH v12 and ISO 27001 Certified Lead Security Auditor, I help startups, SaaS companies, and enterprises secure everything they build and run from a single web app to multi-cloud infrastructure, AI/ML systems, and full compliance programs. My approach is simple: security isn't a scanner dump, it's a clear view of your real risk plus a prioritized, actionable plan to fix it. Coming from a strong software engineering background, I read source code, follow data flows, and reason about architecture, so I catch the business-logic and design flaws that automated tools always miss. 🌐 APPLICATION SECURITY & PENETRATION TESTING Full-stack web, mobile, and API pentesting across the OWASP Top 10 & API Security Top 10: broken access control, IDOR, SSRF, injection (SQL/NoSQL/command/template), XSS, CSRF, insecure deserialization, auth/session flaws, and business-logic abuse. Apps built on React, Angular, Vue, Next.js, Node.js, Python (Django/Flask/FastAPI), Java (Spring), PHP (Laravel), Ruby on Rails, .NET, and Go, plus Android/iOS (OWASP MASVS). Every finding is manually verified to remove false positives, CVSS-scored, and shipped with developer-ready remediation and a free retest. Tools: Burp Suite Pro, OWASP ZAP, Nmap, Metasploit, Nuclei, sqlmap, Nessus, ffuf. ☁️ CLOUD SECURITY ( AWS, AZURE & GCP) IAM and least-privilege reviews, network segmentation (VPC/VNet, security groups, NACLs), encryption/KMS, logging and monitoring (CloudTrail, GuardDuty, Azure Defender, GCP Security Command Center), and CIS Benchmark hardening aligned to Well-Architected security pillars. I find misconfigurations, exposed storage (S3/Blob/GCS), over-permissive roles, and privilege-escalation paths, and design secure cloud architectures with CSPM tools like Prowler and ScoutSuite. ⚙️ DEVSECOPS & INFRASTRUCTURE SECURITY Security built into CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, CircleCI, Azure DevOps), container and Kubernetes security (image scanning with Trivy/Grype, RBAC, network policies, Pod Security Standards), and Infrastructure-as-Code review for Terraform, CloudFormation, Ansible, and Pulumi (Checkov, tfsec, Terrascan). I integrate SAST, DAST, SCA, and secrets scanning (Semgrep, Snyk, SonarQube, Gitleaks, TruffleHog) into automated pipelines, with secrets management via HashiCorp Vault, AWS Secrets Manager, and cloud KMS securing the full software supply chain from commit to deploy. 🤖 AI / ML SECURITY I secure AI, ML, and LLM-powered features against the OWASP Top 10 for LLM Applications and the MITRE ATLAS framework: prompt injection, jailbreaks, sensitive-data and training-data leakage, insecure output handling, model denial-of-service, supply-chain risks, and excessive agency in autonomous/agentic systems. I review apps using OpenAI, Anthropic Claude, and open-source models (Llama, Mistral), plus RAG pipelines, vector databases, TensorFlow, and PyTorch and leverage AI defensively for security automation and faster threat detection. 📋 GOVERNANCE, RISK & COMPLIANCE (GRC) As an ISO 27001 Lead Auditor, I lead ISO 27001:2022 implementation, internal audits, gap analysis, ISMS development, Statement of Applicability, and risk treatment plans to get you certification-ready. I also support SOC 2 (Type I & II), GDPR, HIPAA, PCI-DSS, and NIST Cybersecurity Framework alignment, including security policies, risk registers, vendor/third-party risk management, awareness training, and audit-ready documentation. 🧠 SECURITY ENGINEERING & RESEARCH Secure code review across multiple languages, threat modeling (STRIDE, attack trees), reverse engineering (including Java/bytecode and anti-tamper analysis), malware analysis fundamentals, network security, and security architecture design. I also build cybersecurity training programs and translate complex risk into language both executives and developers understand. 🤝 HOW I WORK 1️⃣ Free scoping call to understand your stack, goals, and concerns 2️⃣ Testing/assessment with clear, regular communication 3️⃣ A prioritized report - Executive Summary + technical detail + exact fixes 4️⃣ A free retest and debrief once your team remediates Every engagement is handled with strict confidentiality and full authorization. I don't oversell if you don't need a service, I'll tell you honestly. 📩 Message me with a few details about your project and I'll reply with practical, no-pressure next steps.

Security Engineer | Penetration Testing | Bot Mitigation | Incident Response | Application Security I work as a Senior Security Engineer where I deal with large scale security challenges daily, from bot networks and web abuse to vulnerability assessments and incident response on platforms serving millions of users. My background covers the full security lifecycle: Offensive security Vulnerability assessment and penetration testing across web applications, identifying weaknesses before attackers do. Experience with VAPT engagements covering OWASP Top 10, authentication flaws, injection vulnerabilities, and business logic issues. Defensive security Bot mitigation, web abuse detection, WAF configuration, rate limiting, and traffic analysis. I have dealt with everything from credential stuffing and account takeover attempts to large scale scraping operations and store cloning attacks. Risk and compliance Threat modeling, architecture risk assessments, and security reviews helping businesses understand their attack surface and prioritise what to fix first. Incident response Investigating active breaches, tracing attack vectors, containing damage, and hardening systems post incident so it does not happen again. Some specific problems I help businesses solve: Unauthorised account access and breach investigations, bot traffic and automated scraping, fraudulent analytics inflation, store cloning and product theft, credential stuffing, checkout abuse, WAF setup and tuning, and ongoing security monitoring. My approach is practical not theoretical. I start by understanding exactly what is happening before recommending anything. Whether that is analysing traffic patterns, reviewing access logs, or running a proper vulnerability assessment the goal is always targeted solutions that fix the real problem. New to Upwork, not new to security.
