What I'm looking for

I am looking for a role that allows me to provide high-value data entry and reporting support while continuing to grow into business analytics.

I am a meticulous and business-minded Reporting Assistant with a trained background in data analysis. My expertise lies in transforming disorganized datasets into clear, actionable insights. With proven skills in Excel and Power BI, I bring structure, clarity, and reliability to reporting workflows. I am known for my ability to clean, organize, and compile reports that decision-makers trust, helping remote teams stay informed and efficient.

Currently, I am working as a Reporting & Sales Data Support at Oxford Test Prep, where I enter and validate high volumes of sales data into reporting templates. My role involves ensuring data accuracy and formatting consistency, which supports business reporting processes. I have also completed a Data Analyst Internship at Quantum Analytics NG, where I transformed raw datasets into clean formats and built dashboards in Power BI to reveal trends and actionable insights.
