Englishالإنجليزية
A one-week course built on Gaurav Sen's System Design for Beginners video (freeCodeCamp.org), cut into short lessons that each play their own piece of the video and continue where you stopped. You design a live streaming service from requirements to API, database, protocols, video processing and CDNs, then do the low-level design with UML and code. A final module covers the building blocks every interview expects: load balancers, caching, sharding, replication, queues and the CAP theorem. Every module has notes, a practical task, a written answer and a quiz.
Each module ends with tasks. The next module opens when they're done.تنتهي كل وحدة بمهام، وتُفتح الوحدة التالية عند إنجازها.

The building blocks every interview expects
no video
Each lesson plays only its piece of the video and continues from where you stopped. Watch the piece, then read
the notes under it: they explain the words the video uses quickly and add what a beginner usually misses.
How the video teaches
The whole video designs one system: a live streaming service (think of a sports match streamed to millions of
viewers). It goes from requirements, to the big boxes and arrows (high-level design), to the classes and code of
one part (low-level design). Keep a notebook open and draw along: system design is learned with a pen.
Before you start
You should know one programming language and what an API and a database are.
Paper and pen, or a free drawing tool such as excalidraw.com or draw.io.
