About

I build production AI systems that ship — from MCP servers to RAG pipelines to LLM agents.

Specialized in LLMs, LangChain, and Model Context Protocol. I've built RAG chatbots, network monitoring pipelines, and AI agents for enterprise clients. Currently deepening expertise in LLMOps, AI agents, and deployed Python systems.
