Need an AI/LLM application pentested before launch? I'm a CREST-registered, OSCP-certified penetration tester currently doing product security at HackerOne. In the last 7 years I've found vulnerabilities reported in the Hall of Fame at SkyScanner, Under Armour, Western Union, Binance, and Intel.
AI/ML Security Specialist & Senior Penetration Tester | OSCP • CREST CRT • CREST CPSA • ISC2 CC • ISO 27001 LA | 7+ Years | Currently Product Security @ HackerOne
I help AI startups and SaaS companies ship products that don't get breached. My focus: securing LLM applications, MCP servers, agentic systems, and the REST/GraphQL APIs that power them — using the same offensive playbook that earned me Hall of Fame recognition from SkyScanner, Under Armour, Redox, Western Union, Indeed, Binance, and Intel.
━━━━━━━━━━━━━━━━━━━━━━
AI / ML SECURITY (PRIMARY)
━━━━━━━━━━━━━━━━━━━━━━
✅ LLM Vulnerability Assessments aligned with OWASP Top 10 for LLM Applications (2025) — prompt injection, sensitive info disclosure, supply-chain, data/model poisoning, improper output handling, excessive agency, system prompt leakage, vector/embedding flaws, misinformation, unbounded consumption
✅ AI Red Teaming using PyRIT, Garak, DeepTeam, PentAGI, Strix — single-turn + multi-turn jailbreaks, indirect injection, tool-poisoning, RAG poisoning
✅ Model Context Protocol (MCP) Security — auditing MCP servers/clients for tool poisoning, OAuth/token theft, command-injection (CVE-2025-6514, CVE-2025-49596 class issues), capability-confusion, and STDIO RCE patterns
✅ Threat Modeling for Generative AI mapped to MITRE ATLAS + NIST AI RMF + OWASP Agentic AI Top 10 (Dec 2025)
✅ MLSecOps & AI Security in CI/CD — automated red-team pipelines via N8N, Nuclei, ars0n framework, OWASP Nettacker, integrated into GitHub Actions/GitLab/Jenkins so every model + prompt change is tested before merge
━━━━━━━━━━━━━━━━━━━━━━
TRADITIONAL VAPT (SECONDARY)
━━━━━━━━━━━━━━━━━━━━━━
✅ Web App & API Penetration Testing — Django, FastAPI, NestJS, REST, GraphQL with Burp Suite Pro
✅ OWASP Top 10:2025 + OWASP API Top 10 — IDOR, SSRF, auth bypass, business-logic flaws, mass assignment, JWT/session attacks
✅ Mobile (Android/iOS), Network (internal/external), Cloud (AWS/Azure/GCP) pentesting
✅ Smart Contract Security Audits — Solidity, common DeFi attack patterns
✅ DevSecOps — SAST/DAST integration, WAF tuning, secure-SDLC consultation
━━━━━━━━━━━━━━━━━━━━━━
