Che Onu

AI Engineer with 13+ years spanning backend engineering, cloud infrastructure, and DevOps — now converging into building production agentic and GenAI systems in Python. Where most AI engineers stop at the model, I own the code, the pipeline, and the infrastructure — end to end.

About

Started writing software and automation tooling at scale, moved into SRE and MLOps to understand how complex systems survive the real world, and now applies that full-stack instinct to AI: architecting multi-agent pipelines with LangGraph and CrewAI, building RAG systems with vector search, and deploying LLM-powered applications that don't just work in demos.
