    Mario Roberto Jimeno Fernández

    Senior Data Engineer

    • 18+ years
    • [ Guatemala City, Guatemala ]

    Builds and maintains production data infrastructure behind analytics, dashboards, and billing. Works across the AWS stack, orchestrating pipelines with Airflow and doing the heavy lifting with Spark, Snowflake, and Python. The results show up in real numbers. Cut cloud spend by 95 percent on one engagement and brought tenant onboarding down from three days to about twenty minutes on another. Moved analytics jobs that once needed a single server with 300GB of RAM onto EMR clusters, so the heavy work now runs on managed instances. Keeps hundreds of Airflow DAGs healthy each day and treats a silently failing pipeline as a bug worth chasing, not something to wait out. Has shipped data work for retail, advertising, and job platforms across the US and LATAM.
