What I'm looking for

I'm looking to build and optimize cloud data pipelines, models, and dashboards that improve business decision-making, collaborating with technical and business teams in an international environment.

I've delivered data models, BigQuery-backed Power BI dashboards, and automated Cloud Functions ingestion workflows for L'Oréal projects at Ayesa Digital. I also support production environments through Hypercare, using T-SQL to protect business continuity and data quality.

Across NTT DATA, Lenovo, Banco del Sol, HUAWEI, Semantec, and Essentium Group, I've built ETL processes, SQL databases, SSAS models, and analytics for international, banking, telecom, oil and gas, and commercial teams. I use SQL, Python, Power BI, GCP, Azure, AWS, Databricks, SSIS, Talend, and Qlik to turn complex data into practical reporting and better decisions.
