  Senior Data Scientist

  The team I worked with generates millions of order decisions every day as part of a fully automated and cloud-based SaaS solution for large retail customers. Daily scheduled data pipelines allow the optimization algorithm to consider the latest data while incorporating uncertainties and constraints to deliver the best decisions to customers in a timely manner. I worked on- scaling an existing analytics tool using a dask cluster,- setting up a Flask service with a PostgreSQL database including ETL pipeline in Azure that can be communicated with via a REST API,- configuring Apache Airflow DAGs,- creating and customizing sophisticated SQL queries including CTEs for an Exasol database,- integrating complex data structures into a data pipeline written in Python,- making necessary adjustments to the partitioning model for the parallelization solution and- improving the optimization algorithm written in C++ and extending it with new features.maximize overall profitability. عرض أقل
