Leeon JohnAI Engineer

I build complex AI systems with a focus on multi-agent inference engines, reliable RAG pipelines, and automated LLM evaluation. Turning research into production-grade systems.

Featured Systems

Multi-Agent Inference Engine

OrionAI

A robust multi-agent system orchestrating Planner, Retriever, Executor, and Critic agents. Features Redis-backed memory, structured JSON logging, and autonomous retry logic for complex pipeline execution.
