Customer-focused Application Support Officer blending technical troubleshooting with relationship-driven service delivery.
NigeriaWhat I'm looking for
I am a dedicated Application Support Officer with over 7 years of experience delivering customer service and technical support across finance and commercial environments. I combine technical troubleshooting, SLA-driven service delivery, and empathetic communication to resolve client issues efficiently.
In my current role at Central Securities Clearing System, I manage multi-channel client inquiries, facilitate user onboarding, and collaborate with development teams to escalate and track incidents to resolution. I proactively monitor application performance and drive continuous improvement to maintain high service quality.
Previously, as a Sales Manager, I prioritized customer satisfaction, nurtured client relationships, and contributed to a 200% revenue increase through strategic initiatives and team leadership. Earlier experience as an IT Help Desk Specialist sharpened my diagnostic skills, remote-support techniques, and training capabilities.
I hold certifications including PMP and ITIL Foundation, and I bring a structured, process-oriented approach to incident, problem, and change management. I seek opportunities where I can apply technical expertise and stakeholder engagement to improve user experience and operational outcomes.
