About

Hi, I'm Moritz. I'm pursuing a Master's degree in Data Science, focusing on algorithms and machine learning.
In my studies I got to work on some open-source technologies, including NumPy and MathCAT (see projects section).

Previously I worked as a data scientist in SaaS, where I gained experience with modern cloud infrastructure, business intelligence (primarily financial controlling and product analytics), and integration of AI foundation models.

Before that, I was a teaching assistant, undergrad research engineer working on algorithms, a software engineering intern for a social app and freelance math tutor during high school.

projects

• Powersort
  Together with Prof. Sebastian Wild, I implemented Powersort (the sorting algorithm used in CPython) for NumPy. I'm also working on a blog post about Powersort.
• MathCAT
  MathCAT is used in assistive technologies including NVDA and JAWS to support blind people to work with mathematics.
• FixCon
  implementation and benchmark of a optimization framework for algorithms research.
• Sipura
  a library of graph algorithms that is based on tooling needed for my Bachelor thesis, and has been used for some theses since. Unlike many similar libraries, it documents each implementations runtime complexity.
• Solver for Vertex Cover
  Winning entry from a hackathon during undergrad.
