Laiz Cristina Mello
@laizcristinamello
Data engineer at Gravitad shaping client data architectures and pipeline strategies, with experience building ETL pipelines for sensor networks and energy forecasts.
NetherlandsWhat I'm looking for
At Gravitad, I define the technical foundation for client data projects, from tool selection and target architecture to pipeline approach. I assess existing data stacks and turn business requirements into processing strategies and reports that inform engineering decisions.
Previously, I built and maintained pipelines for FieldPRO’s automatic sensor network and Casa dos Ventos’ energy price projections, and developed ETL pipelines for environmental and emissions datasets at Lentz. I’ve automated transformations with dbt and worked with Databricks, Spark, Airflow, GCP, and AWS.
