Juan Herrera

I'm an incoming Data Scientist at Ramp.

In the past, I worked at NBCUniversal, Nestlé Purina and Eventellect. I obtained my masters from USC.

Some of my areas of interest include machine learning, statistical modeling, and causal inference.

I'm constantly seeking to understand the 'why' behind things, and as a result, I write about what I learn in the process on Medium and Substack
