Current/Past Positions (see LinkedIn for longer history)

Machine Learning Engineer (NLP) - Spotify (2020 - current)

I build, maintain, and improve machine learning (mostly NLP and NLU) models that power the Spotify Voice system and serve millions of users in real-time.

Data Scientist - Amazon (2017 - 2020)

I worked on many ML projects as part of the ML Solutions Lab at AWS, including NLP, time-series, classification, and more. I also spent time in Alexa working on NLP/NLU models.
