Joseph okpono

I am a detail-oriented data analyst with experience transforming complex datasets into actionable insights using Python, SQL, Power BI and Tableau. I combine statistical analysis, predictive modelling and polished presentation to support strategic decisions.

I have led large-scale dashboard and reporting programs for public health, education and energy, and designed end-to-end SQL systems for student registration and performance tracking. I analysed over 712,000 NHS cancer referrals to uncover a 30% decline in 62-day compliance and developed targeted recommendations for diagnostics and escalation.

In consultancy roles I have driven ETL and cloud migrations, improved query automation and reduced operating costs through data warehousing and bespoke dashboards; I built geospatial and SIMD-driven visual tools and delivered insights that informed policy on EV rollout, rural retrofit and resource allocation. I routinely produce clean, story-driven visualisations and automated reports to enable rapid, data-informed decisions.

With an advanced quantitative background and prior senior geoscience experience in field development, reservoir modelling and exploration, I bring technical rigor, stakeholder management and mentorship to cross-functional teams. I am ready to apply my analytical skills to help dynamic organisations achieve measurable impact.
