What I'm looking for

I want a role where I can secure and automate IT systems, own backup/disaster recovery, and support accurate accounting operations—working with a collaborative team on audits, reliability, and continuous efficiency improvements.

I’m a result-oriented System Administrator and Accounts Administrator who leverages technology to streamline operations, improve efficiency, and ensure compliance with accounting standards. In my recent role at Nigerian Institute for Trypanosomiasis Research (NITR), I designed and implemented a comprehensive disaster recovery plan with an RTO of 4 hours and an RPO of 15 minutes for critical systems, while setting up, configuring, and troubleshooting LAN networks using SME devices.

Across my experience, I’ve reduced manual work by 50%, increased overall system efficiency by 30%, and strengthened reliability by building backup and data recovery plans that led to an 80% reduction in data loss incidents and minimized downtime during system failures. I’ve also supported accounting operations—processing invoices and receipts with a 20% reduction in payment processing time, maintaining 99.5% data-entry accuracy, and contributing to 98% accuracy in quarterly reports—while conducting system and security audits and reducing the risk of security breaches by 25%.
