• Provided software design and DevOps support on a core project to identify construction sites in satellite imagery using segmentation models at scale.• Authored a STAC imagery ETL engine to create time-series distributed “data cubes” of imagery using Dask, for use in model training and inference processes. This library processed 34 million square kilometers of Sentinel2 L2A imagery at a cost of less that $0.10 per square kilometer.• Developed a set of CloudFormation Templates and Helm Charts to bootstrap several Kubernetes environments containing a suite of machine learning applications which enabled an economical and scalable machine learning workflow for data scientists.• Designed a PostGIS PostgreSQL database to store millions of annotations, with associated scripts to efficiently export several thousands of them to stakeholders.• Created Airflow DAGs to automatically ingest annotations related metrics produced by segmentation models to support manual and automated QA.
