AI Infrastructure Engineer | Agents, Vector Search, Real-Time Systems

Most AI projects fail not because of models, but because the infrastructure, data flow, and retrieval systems aren’t designed correctly. That’s where I come in. I design and build production-grade AI systems: from autonomous agents and knowledge graphs to real-time data pipelines that scale. I’m a technical founder and senior engineer with 14 years of experience building low-latency, high-throughput systems used by millions of users and processing billions of events daily. What I can help you build: - AI agents that actually work in production (not demos) - Retrieval-augmented generation (RAG) systems with strong relevance + latency - Knowledge graphs + structured data systems for AI - Real-time AI pipelines (classification, scoring, recommendations) - Vector search + embedding infrastructure at scale - End-to-end backend architecture for AI products (or any product)
