Data & AI Engineering, visualized.
Short animated explainers on SQL, data engineering, data analysis, AI/ML and data system design, made to help you understand concepts and prepare for interviews.
What you'll find: Instagram Reels, YouTube videos and Shorts that show data moving through each step: how a query executes, how a join matches rows, how a window frame slides. Every code snippet shown on screen is executed and checked before it is published.
About the QueryUnstuck Publisher app
QueryUnstuck Publisher is the internal tool we use to publish our own videos to our own Instagram and YouTube accounts and to read the performance metrics of those posts. It is not offered to other people and does not access anyone else's account. See the privacy policy for details.
