Data Engineer building scalable PySpark and AWS pipelines for business-ready analytics.
BrazilWhat I'm looking for
I'm a passionate Data Engineer with a strong track record designing and operating end-to-end data pipelines using PySpark and AWS to transform raw data into business-ready insights.
At ALELO I build EMR-based data pipelines across Bronze, Silver and Gold layers, orchestrate workflows with Apache Airflow, and use S3 and Athena to deliver reliable analytics. I monitor and track tasks through Azure DevOps and participate actively in agile ceremonies.
Previously I developed ETL pipelines with Informatica PowerCenter, optimized advanced SQL across Oracle and SQL Server, and created Power BI dashboards to support public health decision-making. I also collaborated on machine learning pipelines using Python libraries such as Pandas and Scikit-learn.
I hold postgraduate training in Data Engineering and Architecture and bring cross-cultural experience from living in the U.S.; I'm open to remote international roles where I can contribute to cloud migrations, modern data stack architecture, and high-impact data products.
