🎖 Top Rated | 50+ clients | 10+ years building production backend & AI systems You've started building with AI — and the cracks are showing. Hallucinations you can't explain, agents that go off-script, a RAG pipeline that retrieves the wrong context half the time. A demo that impressed everyone and then fell apart on real data. That's exactly where I come in. I build LLM-powered systems that survive production: AI agents, RAG pipelines, and automation built on the data infrastructure they depend on. I work deep in the LangChain/LangGraph ecosystem with Anthropic (Claude API), OpenAI, and open-source models, shipping real products and internal tools for clients in fintech, GovTech, real estate, and edtech. Recent work: • Contract-bidding SaaS for US government procurement — AI agents monitor procurement portals, score opportunities against millions of records, and draft bid responses, cutting manual research time by 80% • Academic integrity platform using LLMs and ML to analyze writing patterns across 50,000+ monthly submissions • Real estate intelligence platform — 60+ concurrent scrapers feeding AI parsing and enrichment pipelines into a multi-region PostgreSQL system Where I spend most of my time: • Designing agent workflows with LangGraph, Make/n8n, and custom orchestration • Building RAG systems that are actually reliable — chunking strategy, retrieval tuning, eval pipelines • Wiring LLMs into FastAPI/Django backends with proper async handling, streaming, and error recovery • Deploying on AWS with Docker/Kubernetes, keeping costs predictable and latency sane at scale The difference: my foundation is 10+ years of backend engineering - Python, FastAPI, Django, PostgreSQL, SQLAlchemy, Celery, Redis, web scraping at scale. I don't just prompt-engineer. Most AI projects fail at the data layer, not the model - I build both. I'm selective about projects. I work best when there's a real problem to solve and a client who wants to understand what they're building, not just receive a black box. If that sounds like you, send me a message with a couple of lines about what you're building.

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.
