About Marina

Hello, I hold a degree in Business Administration and Management (ADE). My professional focus is not limited to processing numbers; I combine technical analysis with strategic business vision to help you optimize your company's profitability and keep your finances under control.
I specialize in organizing chaotic databases, structuring financial information, and designing visual reports (dashboards) that allow you to see the real state of your business at a glance.

How can I help you?
-Data Cleaning and Transformation: Removal of duplicates, correction of formatting errors, and structuring of financial databases to make them functional and reliable.
-Advanced Financial Analysis: Evaluation of financial statements, cost analysis, calculation of profit margins, and detection of budget deviations.
-Reporting and Dashboards: Creation of dynamic and visual reports in Excel or Google Sheets for quick, data-driven decision-making.
-Template Automation: Optimization of spreadsheets so you don't have to waste hours doing the same manual work every month.

Why work with me?
-Business Acumen: By understanding corporate finance, accounting, and management, I know exactly which data is critical for your business and how it should be presented.
-Accuracy and Rigor: In finance, a mistake can be costly. I work with meticulous methodologies to ensure clean data and 100% accurate reports.
-Clear Communication and Punctuality: I will keep you updated on the project's progress and ensure strict adherence to agreed-upon delivery deadlines.
