System Design · by sector

The AI writes the code. You design the system.

Each lesson is the complete system design of one company: how it works, every piece, and why it's built that way — with the moments it was put to the test as real cases inside. Pick a sector, pick a company.

The same companies, from the data side: where every event comes from, how much there is, how it's modeled, moved, scheduled and checked — the things a data engineering interview (or a new data platform) asks you to design.
