What I'm looking for

I’m seeking MEL/M&E specialist roles with donor-funded and international development programmes.

At the World Health Organization, I analyze routine immunization and surveillance data across local government areas, turning validated datasets into reports and dashboards that inform decisions.

As a Data Analyst, I reconciled administrative, surveillance, and campaign data, reducing discrepancies by 30%. I also identified zero-dose gaps in five underperforming LGAs, informing resource reallocation and microplanning.

In my current Technical Officer role, I support LGA health teams with data quality audits and reporting. I’ve mentored more than 40 health workers and coordinated monitoring that achieved over 95% reporting compliance in supervised facilities.

My background also includes research services across social science disciplines and postgraduate study in public health, international affairs, and diplomacy. I’m open to MEL/M&E specialist roles with donor-funded and international development programmes.
