Hi, I'm Emmanuel

I'm a Machine Learning Engineer with 1+ year of hands-on experience building and deploying production ML systems — not just notebooks. I've shipped two production-ready systems: a fraud detection model (79% F1-score, 81% precision) and a customer churn prediction API (84% accuracy), both containerized with real CI/CD pipelines.

I build end-to-end ML pipelines — from data versioning and experiment tracking (DVC, MLflow) through CI/CD deployment (GitHub Actions, Docker, FastAPI) — turning model output into decisions business teams actually use.

My core toolkit is Python, Scikit-Learn, XGBoost, MLflow, DVC, Prefect, Docker, and FastAPI. I'm also actively expanding into deep learning, cloud infrastructure (AWS, Kubernetes), and LLM-based agents.

Kind Words

What mentors and peers have said about working with me.

“Emmanuel’s ability to take a raw idea, structure the data, and ship a containerized API in under two weeks was remarkable. He thinks like an engineer, not just a data scientist.”

— Dr. Sarah Mwangi
Senior Data Scientist, ATC

“I was impressed by his MLOps discipline. He didn't just train a model; he versioned the data, tracked experiments, and made the whole pipeline reproducible. That's rare for a junior.”

— James Oduor
ML Engineer, Freelance Mentor

“Emmanuel is collaborative and explains complex ML concepts clearly. He was a key contributor to our fraud detection project, and his deployment work was flawless.”

— Amina Hassan
Project Teammate, Data Scientist
