What I'm looking for

I seek remote/global roles where I can design scalable data platforms, automate ETL, and build BI solutions that foster data-driven culture and measurable operational improvements.

I am a performance-driven data engineer and BI developer with a proven record architecting Data Warehouses, automating ETL pipelines, and delivering impactful visualizations. I focus on reducing operational overhead and enabling data-driven decision making across organizations.

At JaguaFrangos / Grupo BTZ I led the end-to-end design of the company's first SQL Server Data Warehouse using Talend, migrated 50+ manual reports into automated, auditable pipelines, and created curated SQL views that cut IT reporting requests by 80%.

I build scalable backend services and dynamic frontends, having worked with C#, Java (Spring Boot), Angular and React, and I champion innovation — for example, developing a real-time 3D mobile stock visualization in Power BI to replace manual warehouse audits.
