What I'm looking for

Seeking a fully remote role in Data Analysis, Data Quality, Reporting, or Business Intelligence. I’m eager to use Excel, Power Query, Python, and Power BI to solve business problems, improve data accuracy, and support data-driven decisions across industries while continuing to grow professionally.

I am a data-driven professional with experience in data analysis, data quality management, business intelligence, data validation, data migration, and process improvement. My background includes working with large datasets, identifying inconsistencies, standardizing information, reconciling records across multiple sources, and transforming complex data into reliable information that supports operational efficiency and business decision-making.

I have hands-on experience with Microsoft Excel, Power Query, Power BI, DAX, and Python-based ETL processes. Throughout my experience, I have analyzed tens of thousands of records, developed centralized databases, investigated data-quality issues, supported system migrations, and contributed to data-governance initiatives. I enjoy identifying patterns, solving problems, improving workflows, and finding practical ways to make data more accurate, accessible, and useful.

My professional strengths include analytical thinking, attention to detail, problem-solving, process optimization, documentation, and cross-functional collaboration. I am comfortable working with structured information, investigating discrepancies, identifying root causes, and communicating findings to support informed decisions and continuous improvement.

I am interested in remote opportunities in Data Analysis, Data Quality, Business Intelligence, Reporting, Data Operations, Data Management, and Operations Analysis across different industries. I am particularly interested in positions where I can apply my analytical skills, technical knowledge, and quality-focused mindset to improve business processes, support strategic initiatives, and deliver measurable results.

I am motivated to continue developing my technical skills while contributing to collaborative, data-driven teams. I value accuracy, efficiency, continuous learning, and the opportunity to turn complex information into actionable insights that create meaningful business value.
