Welcome to System Design, but Simple!

Who runs this newsletter?
System Design, but Simple is written by Stephane Moreau (me).
I’ve been a Senior Engineering Manager for close to a decade now.
I’ve interviewed hundreds of engineers, designed real-world large-scale systems, and seen what works and what doesn’t.
I started out as a self-taught developer, and quickly moved into engineering leadership. Along the way, I had to teach myself system design. Now, I’m making it easy for you.
My promise to you:
I will never skip a week. Simple.
Interview-ready content. Every concept will help you pass your system design interview.
I won’t overcomplicate things. System design should be easy to understand, so I’ll make sure it is.
