    Tasks performed in an Agile SAFe and Data Mesh context:

    • Implementation of a CI/CD pipeline for dbt on GCP (via CloudBees, Cloud Run, Git), with automation of tests, validations, deployments, and executions via integrated pipelines.
    • Optimization of analytical processing on BigQuery: writing performant and scalable SQL queries, with a focus on cost reduction and resource governance.
    • Design and deployment of data orchestration pipelines via Cloud Composer (Apache Airflow) and Workflows, to trigger processing based on technical and functional dependencies.
    • Support for Data teams: training on tools (dbt, GCP), pair programming, code reviews, guidance on structuring data projects, and co-construction of solutions.
    • Active contribution to Agile SAFe rituals (PI Planning, demos, retrospectives) as a technical referent and data engineer, ensuring GCP and DataOps best practices.
