Hi, my name is

Onyeka Ogbonna.
I build AI systems that ship.

AI Engineer with an MSc in Applied Data Science and a decade of industrial data experience. I build production ML pipelines, evaluated RAG systems and agent workflows, and I build them in public.

About me

My route into AI was not a straight line, and that is the point. I started as a mechanical engineer, spent nine years as a data analyst building failure-prediction models and reporting pipelines for industrial engineering teams, then completed an MSc in Applied Data Science at the University of Sunderland.

That background shapes what I build. I have watched real equipment fail, so my MLOps project predicts machine failure from sensor data. I have worked in compliance-heavy environments, so my RAG system answers questions over regulatory documents with citations, because an unsourced answer is useless in a regulated setting.

Right now I am deepening the production side of the craft through two intensive programmes: a Full Stack Generative AI and Agentic AI Bootcamp and a DevOps, MLOps and LLMOps Engineering Bootcamp. Everything I build is public: the code, the evaluation results and the write-ups.

Writing

Technical write-ups from each project: the decisions, the trade-offs and the numbers.

// first post shipping soon

The first write-up covers building the predictive maintenance pipeline: baseline model, MLflow tracking and what the drift monitor caught. Follow along on LinkedIn or watch the GitHub repos.
