Hi there, I'm @maxpumperla 👋

I’m a Data Scientist and Engineer from Hamburg, Germany. I’m an open source contributor, author of machine learning & technology books, speaker at international conferences and Coursera instructor.

I specialize in Deep Learning and its applications and can build machine learning solutions and data products from first prototype to production. As DL4J core developer, Keras contributor, Hyperopt maintainer and author of a range of open source libraries, I have a distinct view on machine learning engineering and the data science ecosystem.

Here's what I'm up to right now

  • 📖 I’m currently working on a new book with O'Reilly called "Learning Ray", which helps you get started with Ray. I'm writing standalone Jupyter notebooks alongside the book, which you can find in this repo.
  • 🔭 Some of the materials from my courses as Data Science professor at IU can be found here. My teaching centers around programming Python, big data technologies and reinforcement learning at the moment.
  • 🔭 If you have interesting freelance opportunities, don't hesitate to get in touch with me.
  • 💬 Ask me about anything Python or Data Science related. I'm happy to discuss!
  • 😄 Pronouns: he/him
  • Fun fact: I get asked for directions by total strangers all the time, even in foreign countries, and I have yet to figure out why.

Interesting things I've been doing in the past

And here's how you can get in touch with me
