At ALTIPAL S.A., I led the Data Analytics and Business Intelligence team and coordinated analysis across the organization. I developed KPI-based performance reports using Power BI and Pentaho.

I also designed and implemented the company’s ETL processes and Data Warehouse using Pentaho, centralizing information for analysis. I worked with regional managers and senior teams to turn business needs into analytical and reporting requirements.

At HOTEL HACIENDAS TENERIFE, I analyzed guest feedback from Booking.com, Tripadvisor, and Airbnb, identifying trends and recurring issues. I developed an operational planning system connecting booking information with staff availability.

My earlier roles included software consulting at IBM COLOMBIA and customer data and Contact Center work at FENALCO. I’ve also worked with CRM, PMS, Channel Managers, and Booking Engines in hospitality and customer operations.
