What I'm looking for

I’m looking for remote and freelance opportunities where I can handle data operations, clean and validate datasets, build Power BI dashboards and reports, and support teams across time zones with clear communication and deadlines.

I’m a Junior Data Analyst and Data Operations Specialist based in Nigeria, with hands-on experience in Excel, Power BI, SQL, and Python. I focus on data entry, cleaning & validation, visualization, and reporting—turning messy information into clear dashboards and actionable outputs.

Through remote/freelance data tasks, I perform annotation and cleaning, prepare Excel and Power BI reports, and use SQL queries and Python scripts for extraction and analysis. I’ve also taught 4 9 learners basic Excel and Power BI, and I bring that same detail-oriented, deadline-driven approach to supporting remote teams and improving operations with dashboards and performance tracking.
