Who I Am

Scholar, Engineer, Builder

I'm Derrick Ovunda Njobuenwu, PhD — a UK-based Nigerian data scientist, machine learning engineer, and former academic researcher. Born in Rivers State, Nigeria, I came to the UK on a Commonwealth Scholarship, earned my PhD from the University of Leeds focused on Computational Fluid Dynamics, and went on to publish extensively across nuclear engineering and fluid mechanics.

Today I work as a Higher Statistical Data Scientist at the Office for National Statistics (ONS), delivering AI and ML solutions at scale — including a 40× performance improvement on the UK's GDP estimation pipelines. I lead, build, and mentor across cloud platforms, big data, and agentic AI systems.

Beyond the data lab, I've built a growing community under the @donadviser handle — dedicated to helping men master their money, mindset, and masculinity. I believe rigorous thinking and disciplined character are the foundations of real wealth.

I am a member of the Institute of Physics, IChemE, NSE/COREN, and the UK Fluids Network. I hold certifications in Azure AI, AWS Cloud, Neural Networks, and AI Fairness.

Professional Journey

Where I've Built

DEC 2024 – PRESENT
Office for National Statistics
Greater Manchester, UK
Higher Statistical Data Scientist
Leading delivery of reproducible analytical pipelines (RAP) covering the Monthly Business Survey and Construction Surveys — which together represent 96% of the UK economy. Delivered a 40× performance improvement over legacy systems using Python, PySpark, and AWS. Providing analytical assurance across GDP estimation workflows and driving MLOps standards across ONS. Served on the Planning Committee for the inaugural ONS Data Science Conference.

Mastery of Money, Mindset & Masculinity

Helping men deconstruct the path to wealth and personal power.

Beyond the data lab, I've built a growing online community rooted in the belief that true wealth is built on character, discipline, and long-range thinking. Every day I share real insights on the habits and principles that separate those who drift from those who build — drawn from the same rigour I apply to science.

💰

Money

Wealth-building frameworks, financial clarity, and long-term investment thinking for men serious about financial freedom.

🧠

Mindset

Discipline, clarity, patience, and long-term thinking. The mental architecture that underpins every achievement.

🛡️

Masculinity

Identity, purpose, and character. Becoming a man of substance — grounded in values, led by principles.

#DayOf365 — Daily Wisdom Series

"Discipline is not a prison. It is the only door to freedom that actually opens from the inside. Most men are standing at locked doors, waiting for permission. Stop waiting."
