Hi, my name is

Lior Kaufman.

I love anything related to data!

I’m a data engineer who loves working with the latest modern data stack technologies. My goal is to create data products that are not only valuable and scalable, but also well-documented and tested, all while keeping things friendly and approachable.

About Me

I’m a self-taught data engineer who’s enthusiastic about problem-solving and all things data-related. I like to think of myself as a versatile learner with a strong focus on data. I enjoy discovering new databases and delving into their inner workings. What truly piques my interest is understanding the architecture of databases and how they can be employed to tackle various challenges.

I am currently learning: The Rust programming language in hopes of one day building my own database. Right now focusing on building small command line tools and reading Command-Line Rust by Ken Youens-Clark to learn the best practices.

Here are a few technologies I've been working with recently:
  • GCP
  • Snowflake
  • DBT
  • TypeScript
  • Python
  • Rust
  • PostGress
  • ChatGPT
  • Reddis
