What I'm looking for

I seek a hands-on support role where I can ensure system stability, apply SQL and Power BI skills, work with cross-functional teams, and grow in cybersecurity within a collaborative, impact-focused organization.

I am an Application Support Engineer with five years' experience providing IT support, systems monitoring, incident troubleshooting, and user support across banking, fintech, and technology firms. I specialize in SQL database troubleshooting, Power BI dashboards for operational insight, and maintaining secure, stable production systems through strong IT governance and basic cybersecurity practice.

I have supported USSD and SMS banking channels, collaborated with cross-functional teams to improve service delivery, and led workshops and data-driven projects that boosted program visibility and user participation. I focus on root-cause analysis, proactive monitoring, and delivering user-focused solutions that reduce downtime and operational cost.
