About

Portrait of Shawn Ng Hi, I’m Shawn Ng, an AI engineer. I ship production systems by day and spend the rest of the time explaining the hidden computer science behind everyday technology. This site is where the deep dives live: how YouTube decides what you watch, why cache misses kill performance, what actually happens inside a recommendation engine, and what it’s really like to build with large language models in production.

What you’ll find here

Articles: long-form deep dives into algorithms, systems, and AI, written from hands-on experience.
The Vault: a free library of AI prompts for planning, writing, coding, and productivity.
Efficiency Toolbox: the tools I actually use and recommend.

Elsewhere

I also run two YouTube channels, Divide and Quantum (CS deep dives) and Best of the Best in AI (AI), and I’m building Krevaya AI and vidfora. There are a few other projects in the works too, which I’ll announce when they’re ready.

You can find me on Facebook, X, Instagram, LinkedIn, and Threads.
