    • Test pipelines end to end, so every dataset is complete, consistent and traceable to its source.
    • Fix bad production data at its root in the pipeline, never by hand, and own the critical ETL runs.

    Data Engineer & Back-end Developer @ Talan

    • Santander SCIB: distributed Scala/Spark ETL orchestrated with Airflow into the Elastic stack, with Kibana dashboards.

    Data Architect & Python Developer @ Globant · Google / TelevisaUnivision (ViX, ViX+)

    • Ingested hundreds of TB from many sources (Kochava, Google Ads…) with Airflow pipelines on BigQuery, PostgreSQL and MongoDB.
    • Cut data-warehouse costs by over 40% by optimizing BigQuery stored procedures.
    • Infrastructure as code with Pulumi and GitHub Actions; observability with New Relic and Cloud Monitoring.
