What I'm looking for

I'm looking for remote AI or data roles.

At Pronostica, I built and maintained reports and data models in IBM Cognos Analytics, and supported ETL execution and monitoring in SAP Data Services. I also provided Cognos support to help business users access reliable data.

At Compañía de Galletas Noel (Grupo Nutresa), I developed Power Query transformations to automate reporting preparation, cleaned and debugged data from relational databases, and integrated SAP and Analysis for Office as data sources. I also build machine learning models and data apps in Python, and I'm looking for remote AI or data roles.
