Journey

From classroom to founder.

The throughline isn’t one job title. It’s the same instinct in five settings: read the data, fix the system, ship the tool.

    2017

    First data role

    Ghana Health Service · Wa, Ghana

    Started as Data Quality Engineer. Reduced entry errors by 15% and improved reporting consistency across operational systems.

    The first lesson in how organizations quietly break — and where the fixes belong.

    2022

    Data scientist & trainer

    German Institute of Business & Technology · Accra, Ghana

    Designed analytics programs covering SQL, visualization, and machine-learning pipelines. Trained 200+ engineers and analysts across eight African countries. Lifted program NPS from 41% to 70%.

    Each cohort surfaced the same gap between the data and the systems people actually use.

    2024

    Graduate study begins

    Oklahoma State University · Stillwater

    Began the MSc in Business Analytics & Data Science. Joined the International Student Organization as Intern to the Secretary.

    The formal study of how organizations decide, alongside the operational work of running one.

    2025

    Analyst, president, founder

    Infinedi · ISO · Closeout

    Joined Infinedi in Tulsa as Statistical Analyst Intern, building operational dashboards and identity-resolution pipelines for high-volume healthcare data.

    Founded Closeout the same year. Elected ISO President at Oklahoma State.

    2025

    Inside national systems

    Disney Data & Analytics Conference · Orlando

    Presented work at the Disney Data & Analytics Conference exploring large-scale emergency alert systems and national crisis data.

    The kind of brittle, high-stakes plumbing that turns out to need most of the same fixes as a small firm’s settlement workflow.

    2025

    The Closeout concept emerges

    Riata Business Case Competition · High Tech category

    An operational software concept I had been shaping placed 2nd in the High Tech category at the Riata Business Case Competition.

    That concept became Closeout.

    2026

    Scale

    Oklahoma State · Closeout

    MSc completes in May.

    Closeout moves from concept to scale.

2025Proprietary

Devon Energy · Anomaly Detection for Oil & Gas Separators

2023Open source

Leadership & Impact

Building people, too.

The systems matter. So do the rooms that produce the people who ship them.
