Project History
Spotify Music and Podcast Ingestion Pipeline
http://www.spotify.comThe project aimed to refactor the legacy Python-based music ingestion solution into a modern microservice-based processing pipeline using Java.
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.

AudioHarvest SaaS Startup
AudioHarvest provides a quick, easy, and cost-effective way to create podcasts out of existing content. The user can leverage its previous marketing investments in written content and bring them into the audio world.
I founded and bootstrapped the SaaS startup, building a cloud-based—AWS—robust and scalable solution. I also implemented and managed all related technical concerns, including CRM and digital marketing.
