Production AI systems that don't hallucinate, don't burn tokens, and don't break under load — built by an AI Engineer with 15+ years shipping RAG pipelines, LLM agents, and agentic workflows for SaaS and enterprise teams. Most AI contractors deliver demos. I deliver production systems. Before you commit, I'll run a live demo on your actual data — a working RAG pipeline, a trend-intelligence agent, or a Reddit analytics system — so you see real output before a single dollar changes hands. My stack goes from LangChain, LlamaIndex, and LangGraph all the way to custom LLM Ops, cost-optimized inference, and security layers (RBAC, guardrails, compliance). I've shipped multi-LLM agent systems combining Claude, Gemini, GPT, and open-source models — and I own the architecture end to end. Here's what I build: ✅ RAG Systems — semantic + hybrid + BM25 retrieval, reranking, evaluation, and monitoring. Accurate answers, no hallucinations. ✅ LLM Agents & Agentic Workflows — autonomous pipelines that replace manual ops and remove burden from your team. ✅ Evaluations — labeled golden datasets, baseline benchmarking, and LLM-as-judge scoring. ✅ LLM Orchestration — GPT, Claude, Gemini, Qwen, Kimi, and open-source models, cost-optimized. ✅ AI Automations — custom Python pipelines that save measurable time. ✅ Backend & Infra — FastAPI, Node.js, pgvector, Pinecone, Weaviate, AWS, GCP. Request a demo before ordering: ✨ RAG demo — production retrieval pipeline with hybrid search, reranking, and monitoring ✨ Reddit analytics demo — topic clustering, sentiment, trend detection, influencer mapping ✨ TikTok trend-finder demo — real-time trending video discovery with embeddings and ranking logic "We thought we needed AI. What we actually needed was him. He rebuilt our entire approach — cut costs, improved accuracy, and delivered something our competitors still can't replicate." — Head of Growth, B2C SaaS Selected builds: Computer vision models powering a 1M+ download iOS app. Revenue forecasting platform for $50M+ ARR SaaS products. Enterprise-grade RAG knowledge platform with real-time data and security layers. TikTok trend-intelligence agent using LangGraph and multi-LLM NLP pipelines. Send me a message with your idea, your current bottleneck, or just the word 'AI' — I'll tell you exactly how to build it right, or why it hasn't been built right yet. I respond within a few hours.
