What I'm looking for

I’m looking to grow as a Data Analyst by building KPI-focused dashboards and SQL reports that turn raw data into clear decisions. I thrive in teams that value detail, learning, and stakeholder-friendly storytelling.

I’m an analytical Mathematics graduate advancing my Data Science expertise through Google-led training, with hands-on proficiency in Power BI, SQL, and Advanced Excel. I focus on identifying key trends and KPIs using exploratory data analysis and rigorous statistical thinking.

As a Data Science Intern at CODARTECHAFRICA, I clean and preprocess datasets to spot outliers and missing values, then build interactive Power BI and Excel dashboards to track performance indicators. I also use SQL to extract, filter, and aggregate data, translating complex findings into clear, non-technical reports for stakeholders.

Beyond analytics, I strengthen my clarity and impact through teaching and operations work. As an Online Tutor (Mathematics), I structure lessons and assessments while tracking student performance; as a Customer Care Representative, I analyzed inquiries and handled resolutions with strong confidentiality and attention to detail.
