Senior Data Engineer
Dec 2020 - Mar 20221 year 2 months
Project Overview

Catherine automated a previously labor-intensive process involving the weekly generation of device crash reports for the CTO of SKY Technologies in Google Data Studio. This project involved handling KPI data from AWS S3 buckets and BigQuery. She adeptly managed the data, ingested it into BigQuery, partitioned tables, and crafted views for diverse stakeholders. The final result was a fully automated end-to-end report in Data Studio.
