Johan Rodriguez · Data Engineer

Data Engineer with hands-on experience building end-to-end ETL/ELT pipelines, lakehouse architectures, and data products that drive business decisions. I've designed and shipped data solutions in production at a data marketing agency — from ingestion and transformation to the Power BI dashboards that stakeholders actually use.

Currently based in Europe and open to remote roles or on-site positions in Spain (open to sponsorship).
