I reconcile the claim against the record, until the numbers agree.

Built the live monitoring dashboard for NHIA's CEmONC maternal health programme, consolidating claims submitted by two Third-Party Administrators across 53 reporting facilities. The dashboard tracks approvals, rejections and pending items in near real time for the programme's steering committee.

Cross-checked AXA Mansard's summary claims report against its detailed submission and found the two didn't agree: the summary listed claims for 37 facilities while the detailed report covered only 22, leaving 15 facilities' claims unaccounted for. Logged every discrepancy by facility and issued a formal data request back to the HMO.

Built the annual enrolment analysis for NHIA Rivers State, segmenting Gifship (group, individual, family) and Mop-Up registrations by month, and tying enrolment volume to revenue across four income streams.

Consolidated patient-level surgical claims from six VVF (fistula) treatment centres into a single reporting sheet, then compared each facility's previous and most recent submissions month by month to catch late or missing claims before they reached the programme total.

Independent case study on Nigerian facility-level immunisation and delivery data. Tested whether Penta3 vaccine coverage differs between facilities with high vs. low skilled-birth-attendance (SBA) rates, then modelled the relationship between SBA and Penta3 coverage with correlation and regression, choosing non-parametric tests where normality assumptions failed.

A personal Power BI project outside of work: an interactive, filterable dashboard covering every historical Chelsea FC result by opposition, letting you slice results-to-date against any of 24 opponents and see the win/draw/loss split update live.
