Koosha Totonchi
Principal Data Engineer
Learn to design, build, and automate data systems on AWS. Start by modeling data across relational, document, and graph databases—PostgreSQL, MongoDB, and Neo4j—understanding the tradeoffs of each paradigm. Then build cloud data warehouses in Amazon Redshift, designing dimensional schemas and ETL pipelines that extract from diverse sources, optimize query performance, and validate data quality. Explore modern lakehouse architecture with S3, Glue, Iceberg, and Athena, processing data through bronze, silver, and gold layers using Apache Spark. Finally, orchestrate production pipelines with Apache Airflow: scheduling workflows, managing data lineage, and deploying to Amazon MWAA. By the end of this program, you'll be ready to engineer end-to-end data platforms that scale.
