Recommendations

A preview of what LinkedIn members have to say about Aaron:

  • Aaron is a very smart and knowledgeable Data Architect. I worked with him building out the common machine learning infrastructure for Airbnb. He has a strong mathematical and algorithmic background and is able to write user friendly scalable data pipelines very quickly and master new technologies very easily. I love working with him and would highly recommend him as a great technologist.
  • Aaron was a vital component in getting Airbnb’s analytic systems to scale. He replaced R code that wouldn’t scale with C++ and python. Critical pieces of Airbnb’s analytic systems would not exist without Aaron’s work. Aaron understands analytics, and the best route to make it scale.
