I help businesses clean, organize, and validate data to improve reporting quality and support better decision-making. I work with spreadsheets, databases, and business reports, transforming inconsistent or unstructured information into reliable, organized, and easy-to-use datasets.
My experience includes data cleaning and formatting, validation and consistency checks, spreadsheet organization, duplicate and error removal, database structuring, KPI validation, report preparation, and data quality auditing. I also support documentation, categorization, and standardization processes to ensure information is clear and reliable.
I can work with Excel files, Google Sheets, CSV files, SQL databases, operational and business reports, CRM exports, sales and financial datasets, as well as marketing and analytics data. My goal is to deliver organized files, structured datasets, validation reports, and practical solutions that help businesses work more efficiently.
I use tools such as Excel, Google Sheets, SQL and Power BI to provide accurate, high-quality, and well-structured results.
