Using Polars in Rust for high-performance data analysis

Mario Zupan I'm a self-employed Software Engineer and Trainer living in Vienna, Austria. I've worked at several companies and in multiple fields building, maintaining and operating distributed systems at scale using Java, Kotlin, Node, Go and Rust. I also taught advanced software engineering courses for several years at the University of Applied Sciences FH Joanneum in Graz and worked as a technical trainer, empowering other software engineers to reach their full potential. Currently, I work as a freelance software engineer and trainer again, looking to help companies build high-quality software solutions. Check out my personal blog: http://www.zupzup.org.
