What I'm looking for

I'm seeking a data analyst role where I can apply Python, SQL, and visualization to produce actionable insights, contribute to KPI-driven decisions, and grow within a collaborative, data-focused team.

I am a detail-oriented data analyst with hands-on experience in data wrangling, visualization, and generating business insights.

I completed a three-year internship at CHIBEXTEC Enterprise in Benin City, where I used Python, SQL, and Excel to clean and process raw data and develop dashboards for daily, weekly, and monthly reporting.

I created visual reports in Tableau and Power BI to support marketing and operational decisions, collaborated with colleagues to define KPIs, and applied exploratory data analysis and A/B testing to identify performance trends and efficiency gaps.

I hold a Bachelor of Science degree and a Data Analytics Certification from Mikon Institute, and I am committed to applying analytical rigor, clear communication, and problem-solving to help teams make data-driven decisions.
