What I'm looking for

I am seeking a data- or research-focused role with opportunities to apply SQL, Python and Power BI, collaborate cross-functionally, and grow my analytical impact.

I am a results-driven data analyst with hands-on experience in data cleaning, validation, and visualization using Power BI, Excel, SQL, and Python. My background combines practical quality-control work and educational data management, which sharpened my attention to detail and process-focused mindset.

At DM Holdings I conducted analysis of quiz performance metrics and built dashboards and reports that supported cross-functional teams; I collaborated remotely with content and operations to ensure data integrity. Earlier roles in educational institutions entrusted me with maintaining accurate student records and preparing periodic reports, reinforcing my consistency and reliability.

My time in quality control at a manufacturing environment gave me practical experience running tests, preparing samples, and analyzing quality data to improve compliance and efficiency. I completed a data analysis training track at CWW Tech Africa to strengthen my technical toolkit and apply best practices in analysis and reporting.

I seek a data- and research-oriented role where I can apply my analytical skills, contribute to organizational growth, and continue learning; I bring a strong commitment to accuracy, collaborative problem-solving, and clear data storytelling.
