ABOUT ALLAN ABREU
Since 2019 I have been working for a food delivery network as a data engineer developing both the data warehouse and the data ingestion pipeline using mostly Google BigQuery as the data warehouse, Airflow for scheduling and SQL and Python for the programming languages.Before this, I worked with development and maintenance of information systems for a financial institution since 2014. In January 2017 I started working with Agile methodology (Scrum/Kanban) and Big Data technologies, primarily Hive, Impala and Spark inside the Cloudera distribution.Before this, I used to develop and maintain batch ETL workflows using Informatica PowerCenter 9.6, Shell Scripts and Oracle PL/SQL. I also had to draw any changes on the Star/Snowflake Schema of Datamarts and Datawarehouses, as well as changing the SAP Business Objects Universe to allow use of new data.I am passionate about changing and learning new technologies and have a drive to always try and find a solution for a given problem.
