Spotify Music and Podcast Ingestion Pipelinehttp://www.spotify.com
I played a key role in this project that resulted in reducing processing times from days to hours. I also designed and built a new podcast ingestion system, scaling from thousands to millions of podcasts. Additionally, my task was to take ownership and improve Google Dataflow-based podcast publishing pipeline, owning the back-end servers serving all Spotify clients.
