About this gig

Are your AI agents and LLMs putting your business at risk? As you scale with autonomous systems like CrewAI, LangChain, or custom LLMs, you expose your corporate data and APIs to critical threats such as Prompt Injection, Data Leakage, and Unauthorized Code Execution.

I am a Cybersecurity Specialist and AI Researcher. My mission is to ensure your technological innovation doesn't become a security liability. I provide targeted AI Red Teaming and build robust AI Guardrails to keep your applications bulletproof.

What I offer:

  • AI Red Teaming & Pentesting: Simulated attacks to identify vulnerabilities in your LLMs and agents, fully aligned with the OWASP Top 10 for LLMs.
  • Custom AI Guardrails: Python-based input/output validation to block malicious prompts, jailbreak attempts, and PII leaks before they reach your system.
  • Secure Architecture: Containerized Docker environments to ensure your autonomous agents operate with strict isolation and the principle of least privilege.
