Code Smells in Data Science: What can we do about them?
Laszlo Sragner

We all want to write cleaner code but usually don't know where to start. It also doesn't help that most guides available are written for software engineers and not data scientists.

Code smells are a taxonomy and a well-defined set of instructions on how to identify typical antipatterns in your code and change them in a few steps.

In this talk, I will select a short list of typical code smells that frequently appear in data-intensive workflows and walk you through how to resolve them.

Software Engineering Practices in Data Science
Laszlo Sragner, Matteo Latinov

This discussion session focuses on exploring the application of software engineering practices in the field of data science. Join us to delve into essential aspects such as python packages, IDEs, testing, refactoring, and architecture that play a crucial role in building robust and scalable data science solutions. We will discuss how adopting software engineering principles can enhance the reliability, maintainability, and efficiency of data science projects. Whether you're a DS manager or practitioner, this session offers a platform to exchange insights, share experiences, and discover innovative approaches to integrating software engineering practices into the data science workflow.
