Profile

I'm a Senior Data Analyst and Analytics Engineer based in Calgary, Canada, with experience across retail, supply chain, fintech, SaaS, and public sector environments in Canada, the UK, and Nigeria.

I specialise in building the full analytics stack — from dbt transformation pipelines and Snowflake schemas through to machine learning models, statistical experimentation, and executive dashboards. Equally comfortable as a technical builder and a trusted stakeholder advisor.

Currently open to Senior Data Analyst, Analytics Engineer, Data Strategist, and Product Analytics roles. Remote-friendly.
