• Led the team that implemented a reporting and visualization engine for one of Africa’s largest banks used for automated ATM monitoring. This information guided KPI setting for ATM custodians and decision-making regarding terminal location and performance. Reduced ATM unavailability by 60%, and reports were used to justify the redeployment/ commissioning of ~ 300 ATMs. Data volume totaled ~700GB per month.• Worked on the team that successfully piloted a high availability and load balancing solution for one of Africa’s largest banking group’s electronic financial transaction processing system (Postilion version 5). • Documented new systems/ changes to existing systems (both for in-house knowledge management and for customer reference documents). I also posted documentation to http://fepsupport.wordpress.com. • Implemented 17 projects with varying scopes (involving virtualization, databases, national and commercial switch integrations) with responsibility for API testing, application deployment and post deployment support.

• Built and managed the Configuration Management Database (CMDB) of the IT academy• Administered the schools Linux server and school management software• Initiated and managed the school's perimeter surveillance projects.• Created virtualization solutions on Linux to manage operations and reduce project costs.• Informed management and implementing solutions that will improve operations.• Managed the IT academy and supervised the professional courses taught by course instructors.• Trained students and subordinates on Networking and Computer hardware and maintenance• Trained teachers on use of the School management software• Carried our client support for organizations including NTA Lafia and Nasarawa state polytechnic.
