I build and migrate reliable AWS data pipelines using PySpark, Scala, and SQL.
ColombiaWhat I'm looking for
I'm building and migrating banking data pipelines at Inetum, converting legacy SQL and SAS processes into PySpark and Scala solutions on AWS.
I develop, execute, and monitor ETL pipelines with PySpark, Apache Spark, and Control-M. I validate and reconcile source and migrated data using SQL, AWS Athena, and Jupyter/SageMaker.
I troubleshoot workflows across AWS Glue, EMR, Athena, and S3, addressing schema, partition, duplicate, cutoff-date, and Parquet-file issues. I also document solutions, manage code with Git, and communicate risks and progress with technical and functional teams.
Previously, I analyzed technical requirements and developed proposals for industrial automation projects in Oil & Gas, coordinating with engineering, procurement, and client teams.
