At IZZI, I develop enterprise Data Warehouse solutions and ETL/ELT pipelines using dbt, Snowflake, SQL, Matillion, Oracle, and ODI. I build production-ready DataMarts, fact tables, dimensional models, and layered Raw-to-Data-Mart architectures.
For the SKY Mexico and Izzi Data Warehouse integration, I led source discovery for unfamiliar Salesforce datasets and translated business rules into dimensional structures for operational and corporate indicators. My work helped reduce a critical daily process from 6–8 hours to around 1 hour.
I've also supported BI reporting at AT&T with Power BI and Power Automate, and SQL migration automation at ILCE using Python and Pandas. I work with large-scale data, including source tables with 500M+ rows, and use GitHub in Agile/Scrum delivery environments.
