About Javier

For almost nine years, I have worked in an operational environment where information had a direct impact on the company's decision-making. My responsibility was not only to review and audit data, but to ensure the quality of information related to spreadsheets, budgets, resource allocation, and operational processes, detecting inconsistencies and proposing improvements for the area's functioning.
During this time, I discovered that my greatest interest was not just reviewing information, but understanding what was happening behind that data and how to use it to generate better decisions. This led me to self-teach myself advanced Excel, Power BI, and SQL, developing personal projects focused on data visualization, report automation, and the construction of dashboards and KPIs.
Today, I seek to take the next professional step, combining my real operational experience, but this time with modern data analysis tools to add value through more reliable information, clear indicators, and business-oriented solutions. My goal is to continue growing within the analytics area, participating in projects where I can transform data into decisions and continue developing as a professional.
