  • Will Bank
    Data Engineer
    Will Bank Jan 2021 - Jan 2022
    I am a part of a team that works to develop data products, working on receiving, process and making available the most diverse data sources (internal and external APIs, SQL and NoSQL Databases, FTP). I was the main engineer on the data lake Migrate project, leaving a flow with Pentaho Kettle and Redshift and going to a Data Lake structure inside the AWS Cloud. Our main data source is an Oracle with more than a thousand tables and almost 2 terabytes, and by using AWS DMS solution, we brought all this data to AWS S3 creating our Raw Zone. All processing between the Raw and Processed layers was performed by EMR (PySpark) and orchestrated by Airflow. The Processed Zone is the first accessible layer on Data Lake and we use AWS Athena as the SQL engine. In the Curated and Analytic layers, we implemented the Data-Mesh concept, where the business areas are responsible for the rules of each entity within this micro-universe of data. Aiming to obtain more autonomy for the business areas, we use DBT (Data Build tools) as a framework to manage, orchestrate and implement all tables up to the Analityc Zone.
