David M. Andrzejewski

  • 🌉 I am a machine learning and software engineering enthusiast living in the San Francisco Bay Area.
  • 🤖 I am especially interested in applied settings where we can augment or amplify human expertise with machine learning.
  • 🪵 2011-2024 I was at Sumo Logic, helping organizations use machine-generated data to ensure the reliability and security of their software.
  • 📣 2011-2019 (pre-COVID days!) I had also co-organized the popular (> 7500 members, > 18k Twitter followers) San Francisco Bay Area Machine Learning meetup.
  • 🧑‍💻 Before all that, I had been a postdoctoral researcher at LLNL and a PhD student at the University of Wisconsin–Madison.
