Data & AI

Analytics engineering that teams, and their AI agents, can trust.

I'm a Senior Analytics Engineer at Data Culture. I design data models, lead warehouse migrations, and build governed AI analytics agents with evaluation built in. Before that I was a data team of one, then an analytics engineer at Sterling Bank.

Where I've worked

Each step moved the same work closer to the people who use it: a stack built from scratch, analytics engineering inside a bank, then data and AI solutions for many client teams.

Data Culture

Senior Analytics Engineer

Data and AI solutions for client teams: data modelling, warehouse migrations, and governed analytics agents with evaluation built in.

Sterling Bank

Analytics Engineer

Analytics engineering inside a large financial institution on an Azure and dbt stack.

Early-stage startup

First data hire

A data team of one. Built the modern data stack from scratch with BigQuery, Airbyte, Metabase and dbt.

Selected work

A few results I can point to, from client work and from building on my own.

Governed analytics agent

Open source · 2026

Co-built with the Data Culture team: an agent pattern on dbt's agent schema plus an accuracy evaluation framework with an LLM-as-judge fallback. Written up in the Metric Agent Playbook.

A modern data stack from scratch

First data hire

BigQuery, Airbyte, Metabase and dbt, set up and run as a data team of one.

YouTubeDavid Data@daviddata · Data modelling, dbt, pipelines

Teaching on YouTube

A channel for anyone learning data analytics and analytics engineering, from first steps to experienced practitioners. I cover data modelling and architecture, dbt, data pipelines, and the tools shaping the field.

The dbt community helped me build a stack alone. I try to return the favour.

dbt Community Champion

Selected for the inaugural cohort, alongside Opeyemi Fabiyi of Data Culture.

Co-organiser, Lagos dbt Meetup

Running workshops, panels and talks for data practitioners in Lagos.

Head of Programs, Young Data Professionals
