Not a biography. A story about a classroom that never let go, an Android tablet that became a development machine, a degree earned as an adult, and what happens when a 15-year educator finally finds the technical tools β and the faith β to solve the problems he has been watching for 15 years.
My teaching career began before I had a formal degree to show for it β and that matters. I started standing in front of Nigerian classrooms in 2009, and I have not stopped. Not when things got hard. Not when the pay did not match the effort. Not when the tools were broken and the resources were thin.
I have taught across every level of Nigerian education β Nursery, Primary, and Secondary. I am currently teaching at secondary level (JSS1βSSS3) at God of Seed Academy. Across my career I have taught Mathematics, Further Mathematics, Physics, Chemistry, Computer Science, and Basic Technology at over 15 institutions across Lagos and Ogun State.
"Teaching taught me that the hardest part of any problem is rarely the solution. It is understanding the problem clearly enough to know what kind of solution is even possible."

Long before I ever opened a Jupyter notebook, I had a clear and specific ambition: to use technology to solve the problems I was watching every day inside Nigerian schools. The reliance on paper. The manual marking. The zero data on whether students actually understood anything versus simply memorising answers. These were solvable problems. I could see the solutions clearly. I just did not yet have the technical tools to build them.
That ambition is exactly why I went back to university as an adult β to study Computer Science Education at Lagos State University. I graduated in 2023. Then in 2025, the 3MTT programme gave a 15-year problem-solver a technical language. Within months, classroom problems I had been watching for 15 years had pathways to deployed solutions.
The first major build was CBT Pro. Built not because I learned HTML, CSS, and JavaScript β but because I think clearly as a data scientist and leveraged AI to operate competently in an unfamiliar technical field. Android tablet. Acode editor. Zero budget. Real students. Real exams. That is what AI-Augmented Solutions Development actually means.
"The constraint is not the obstacle. The constraint is the brief. I did not wait to become a web developer. I used what I understood about thinking clearly, leveraged AI, and built the tool my students needed."
I am not a web developer who picked up data science. I am not a data scientist who happens to teach. I am an AI-Augmented Solutions Developer β someone who uses clear thinking and AI leverage to build solutions across any domain. That identity has three expressions:
16 EdTech projects β CBT system, LMS platforms, school admin tools, student analytics. Built because I watched the problems up close for 15 years. Home: @hmgacademyhub.
HMG Academy18 DataTech projects β 7 ML models across 7 industries, 11 data tool simulators. Every model documented honestly. Home: @cssadewale / @hmgtechnologies.
HMG TechnologiesEvery platform is a pulpit. Every tool is a testimony. HMG Gospel β dramavangelism, techvangelism, church tools, digital outreach. Home: @hmgospel.
HMG Gospel"Data science taught me that if you can think through a problem clearly, you can find a path to a solution β even in territory you have never entered before."
I never start with a technology. I start with a problem. If the problem is not clearly understood, no solution will be genuinely useful. Fifteen years of teaching this instinct into myself.
CBT Pro was built with no laptop, no web dev training, zero budget. The constraint forced better decisions. I now see constraints as the brief, not the barrier.
Not collecting certificates. Learning with clear direction β understanding why each skill connects to the next, and being honest about what I do not yet know.
Everything I build is designed for Nigerian realities first β slow connections, low-end devices, real classroom constraints. The tools must work for the people who actually need them.
A model nobody can understand is not useful in a classroom or a boardroom. I use SHAP and clear documentation because decision-makers need to trust what the data shows them.
The name His Marvellous Grace reflects a genuine conviction: every breakthrough has arrived as a result of grace I did not engineer on my own. I just kept showing up and doing the work.
Founded in 2015, HMG Concepts began as a one-person tutoring service and has grown into a four-subsidiary organisation β each solving a specific problem in education, technology, faith, or media.
"Building solutions that matter β for learning, for life, for faith, and for data."

Before the data, there was music. I hold certificates in Piano Music and Rudiments of Music from Rotop Music Academy (2013), and I still play piano and guitar. Pattern recognition, structure, rhythm, and the discipline of practising something imperfect until it is right β these are data science skills too, once you know how to look at them that way.
My interests include: Data Research Β· Social Edutainment Β· Reading Β· Playing Piano & Guitar Β· Surfing the Internet Β· Student Mentorship Β· Faith & Evangelism.
And above all β I am still in a secondary school classroom every week. Not because I have to be. Because the problems I solve with data are the same ones I have been watching up close for 15 years. The classroom and the data science are not two separate lives. They have always been the same work, waiting for the right tools.
