I've delivered data architecture, modeling, ingestion, quality, and visualization work for BairesDev, ArcelorMittal, and Vale across nearly 10 years in data and analytics.

At BairesDev, I model and validate data through the Gold layer using Databricks, Delta Lakehouse, SQL, Python, and Power BI to support business decision-making. At ArcelorMittal, I designed ingestion and integration workflows across SFTP, APIs, legacy DBMS, and IIoT devices while helping maintain a growing platform with 50+ schemas and 400+ tables.

At Vale, I supported ITIL analytics through ETL monitoring, SQL optimization, data warehouse delivery, and dashboards in Power BI, SSRS, IBM Cognos, and SAP Business Objects. I also enjoy helping organizations strengthen data literacy and adoption.
