I’m a results-driven IT Infrastructure and Banking Technology Specialist with extensive experience managing enterprise systems in the financial sector. In my current role as Assistant Head, Technology at Sky Bank (Sierra Leone), I lead critical IT operations across electronic banking systems, card management, and infrastructure optimization—driving improvements in system uptime and operational efficiency.

My work spans end-to-end deployment, configuration, and maintenance of datacentre, servers, ATMs, and networks, alongside cybersecurity implementation to safeguard financial systems. I’ve led migrations (Google Mail to Microsoft Office 365), implemented SIEM & DAM security systems, integrated the Orange Money API into mobile banking, and delivered ATM deployment and configuration across all branches—while providing technical leadership and end-user support.
