    I create and maintain software infrastructure to systematize and automate data collection in order to produce constant flows that allow the business to identify trends and patterns in subsequent stages of data unification and centralization. Additionally, I collaborated within a work cell that included a Scrum Master, Product Owner, Analysts, Engineers, and QA professionals, ensuring that our projects adhered to agile methodologies.

    Created and maintained software infrastructure to systematize and automate data collection, enabling the business to identify trends and patterns in subsequent stages of data unification and centralization.

    As a Data Analyst, I answered business questions through the construction of dashboards, developed the Data Warehouse, and integrated various data sources to enhance data quality, ultimately generating a comprehensive 360-degree view of the products sold by customers.

This led to the establishment of a backlog with specific tasks
