What I'm looking for

I’m looking for an entry-level data analyst role where I can use SQL, Python, and Power BI to clean, model, and visualize data—turning insights into actionable recommendations while learning from strong, supportive teammates.

I’m a dynamic and detail-oriented data analyst with expertise in data visualization, statistical analysis, and database management. I’m seeking to leverage skills in SQL, Python, and Power BI to drive business insights and support strategic decision-making.

In my internship at Bytemark Institute (Port Harcourt), I tutored students on the use of Excel and Power BI. I developed data models using Excel and Power BI (Power Query), improving data accuracy by 30%, and built Power BI dashboards that led to a 25% increase in the decision-making process for business insights.

Beyond analytics, I supported the organization as Secretary | Customer Relations, trusted to act as Officer-in-Charge in the Manager's absence. I managed student and client registration end-to-end, handled proactive follow-ups, analyzed operational data with Excel and Power BI, produced well-structured reports, and coordinated schedules and administrative workflows.
