If any of these sound like you, you're in the right place.
I am a lecturer at UC Berkeley, and I have taught 600+ students there.
I made this course to share the pattern that changed how I think about software, and the 7-question cheat sheet I wish someone had given me years ago.
By day 5 you will be able to:
“I find your teaching very valuable and needed for me to get back into the job market.”
When someone says "design Instagram," it is easy to start with technology: MongoDB, Redis, Kubernetes. That is like asking what color to paint the walls before you have designed the house.
You cannot memorize every architecture an interviewer might name. You need a way to start that works on all of them.
Every system you use is built from the same 7 building blocks. Two do work: a Service that answers requests, and a Worker that handles slow jobs in the background. Five hold data: a relational database, a key-value store, a file store, a queue, and a vector database. Instagram, Netflix and Uber are the same blocks, arranged differently.
Ask what the system has to do before you name a technology, because the same blocks show up whatever the tech stack.
The free 5-day course teaches the blocks over five emails, one a day. Day 5 hands you a 7-question cheat sheet: one question for each block, such as "What work can happen later?" Answer them in order and you have the skeleton of any system design.
