Discover our exemplary project: 

Cost optimization on Snowflake data platform

Datumo optimized a Snowflake-based platform for a pharmaceutical company, aiming to reduce costs and enhance ELT processes. Before we stepped in, the Client had to manage 1 petabyte across 200 tables. Airflow orchestrated the platform, using Python scripts for data extraction, focusing on data snapshots with hundreds of millions of records. Strategic use of deltas, external tables, and reduced time travel periods led to almost 50% cut in storage volume.

Analytics engineering on Google Cloud Platform

The project entails creating and improving data pipelines on Google Cloud Platform (GCP) to aid analytics and data science teams. The objective is to optimize data workflows utilizing Cloud Composer (Apache Airflow), BigQuery, and Dataproc (Apache Spark) for scheduling, warehousing, and processing respectively. Key responsibilities encompass optimizing SQL queries for better performance, developing internal libraries to streamline tasks, and advocating for data processing best practices. Additionally, the project offers opportunities for progression into data science or MLOps.
