More about Me.

Currently based in Lagos, Nigeria.

I started in marketing and communications, transitioned into engineering, and spent the years since building across fintech, foodtech, healthtech, edtech, energy, and enterprise telecom. Today I architect and tech-lead high-availability platforms serving millions of users, build AI systems with production-grade reliability, work with Vatrac Labs and BuildSelfAgency, and research Agentic AI at the University of Lagos. The common thread in all of it: I like being the person responsible for whether the system works.

What I do

System design and architecture

I design and own backend systems for high-availability environments, covering data modeling, infrastructure, and DevOps.

AI engineering

RAG pipelines, AI agents, and automation built with evals, guardrails, and proper failure handling. I build the kind of agents that run ten thousand times against real users.

Technical leadership

I lead cross-functional teams through complex deliveries, translate between engineering and stakeholders, and stay accountable from first diagram to production.

Product engineering through Vatrac Labs

For businesses that want a product or AI automation built and run properly, we take on select engagements. usevatrac.com

How I work

(01) End-to-end ownership

I take systems from architecture through infrastructure to production, and I stay responsible for them after launch.

(02) Reliability as a discipline

Years in high-availability environments taught me to design for failure and that discipline carries into everything I build, including AI systems.

(03) Communication that survives translation

I came into engineering from communications, and it shows. I can explain a system to a boardroom and document it for the team maintaining it, in the same afternoon.

(04) Speed with judgment

I ship fast because I've built enough systems to know which corners can't be cut. Speed without that judgment is how production incidents get made.

Research and writing

My current research is on Agentic AI and their application to African economies, part of my masters in Information Technology (AI) at the University of Lagos.

Paper coming soon.

Other Interests

Mathematics

I solve mathematical problems to improve my problem-solving skills.

Map reading

I love to discover new places from the comfort of my home with maps.

Research

My current research area is Agentic AI and their applications to African economies, which is also my Masters degree focus at the University of Lagos.

Books/Movies

I spend most of my free time reading fiction or watching adventure series

French

I'm learning French, slowly and stubbornly.

Entrepreneurship

When I am not writing code, I am working with the team at Vatrac Labs and BuildSelfAgency.
