About

I'm Ayo Mosanya — a data engineer and analytics practitioner with nine years of experience building the systems that help organizations get real value out of their data.

I work across data engineering, analytics, and — more recently — AI tooling. Most of my career has been spent solving problems that are easy to ignore until they're not — pipelines that break quietly, reports nobody trusts, and data infrastructure that was never built to scale. I fix those things and build what should have been there from the start.

How I work

I work best when I can go deep on a problem and stay close to the implementation. I care about systems that actually get used — not just built and handed off. The work only counts if the people on the other side can trust what they're looking at.

I don't hand off blueprints. I build. Then I make sure the people running the system understand what they have.
