Precious Chukwu

I’m a results-driven Data Analyst with 3+ years of hands-on experience collecting, cleaning, and analyzing datasets to generate insights that directly support business decisions. I focus on turning messy, real-world data into clear outputs through rigorous validation, careful data integrity checks, and actionable reporting.

In my current role as a Data Analyst & Reporting Officer (remote, UK), I collect and clean data from internal and external sources, then build and maintain dashboards and reports in Excel and Power BI for daily, weekly, and monthly management use. I verify accuracy, completeness, and consistency, identify discrepancies, and collaborate with relevant teams to resolve issues quickly while maintaining strict confidentiality and data quality standards.

Across international projects in Nigeria and the UK, I’ve built interactive Power BI dashboards, performed exploratory data analysis (EDA) to identify patterns and anomalies, and produced reusable Excel models and BI reports that streamline reporting for stakeholders. I’ve also developed SQL database objects (tables and views) to organize and query supply chain data more efficiently, connecting business policies to operational outcomes for leadership.

I’m proud of delivering measurable impact: I automated a data processing workflow as part of a 6-person team, increasing analytical efficiency by 40% and reducing manual cleaning time; I also contributed insights that supported a 15% increase in monthly revenue by identifying upselling opportunities, while maintaining zero major data errors through strong quality checks. I’m motivated by collaborative, data-driven teams and I continue growing through credentials including Google Data Analytics, Advanced SQL, Microsoft Excel, and Statistics & Machine Learning.
