Deepfakes and voice-cloning fraud are hitting companies that can't afford a breach. I build the AI that stops them, and I deploy machine vision and private LLMs inside your own network, so sensitive data never leaves. Top Rated, 100% job success, nearly a decade in. Most AI freelancers build cloud chatbots. I work the harder, higher-stakes problems: stopping AI-enabled fraud, and running real vision and language models where data legally can't touch a public cloud, for defense, healthcare, legal, and finance. What I do: - Deepfake & voice-biometric detection: fingerprinting and vector analysis that catch synthetic audio and identity fraud - Machine vision & object detection: YOLOv8, OpenCV, and GPT-4 Vision for monitoring, inspection, and threat detection, on-prem or at the edge - Private LLMs & RAG: fine-tuned models and retrieval that run inside your network - Full-stack AI delivery: Python, PyTorch, FastAPI, React, Docker, AWS/Azure/GCP A few results: - A voice-authentication system that hit ~98% accuracy on synthetic speech and shut down voice-cloning fraud - Cut one client's manual monitoring ~90% with a YOLOv8 + GPT-4 Vision surveillance platform - Indexed 500+ legal contracts into a private RAG, saving 200+ review hours with nothing leaving their network If you're fighting AI-driven fraud, or you need real AI somewhere the public cloud isn't allowed, send me the problem and I'll tell you straight whether I'm the right fit.
