What I'm looking for

I’m looking for a data engineering role where I can build reliable, scalable ETL pipelines and optimize Redshift/AWS warehouses with Airflow, focusing on data quality, observability, and measurable cost/performance improvements.

I build and operate data platforms for cross-border payments. At dLocal I designed and maintained more than 100 production Airflow DAGs, optimized Redshift workloads over billions of payment records, and led the technical direction of three finance data projects, including a cost and reconciliation integration on Iceberg and Databricks.

Before that, I worked on the on-premises to AWS migration at Naranja X and consulted on Snowflake for Banco Sabadell, reducing storage costs by 30%. I also created and taught the Big Data specialization at Informatorio Chaco, training 200+ students.

I hold the Astronomer Certification for Apache Airflow 3 Fundamentals and I'm preparing for AWS Solutions Architect Associate. Based in Buenos Aires, C1 English. I care about maintainable pipelines that turn transactional data into trustworthy decisions.
