What I'm looking for

I'm seeking a remote Data Analyst Internship where I can apply my data cleaning, data validation, and quantitative analysis skills to real datasets.

At Self-Employed, I clean, structure, and format raw CSV and Excel datasets, resolving anomalies, missing values, and duplicates before analysis. I also research technical and scientific literature and turn it into structured analytical reports.

In microbiology research projects at Waziri Umaru Federal Polytechnic, I managed experimental data records, interpreted plate counts, and standardized research data for peer review and academic documentation. I hold a Google Data Analytics Professional Certificate and use advanced Excel for data manipulation and reporting.
