About

I'm Milan, and I write Briefcase Study.

Case studies are how system design finally clicked for me. Seeing how a real team broke something and fixed it stuck way better than any course, so I turned them into something you play before you know the ending.

Every case comes from the company's own postmortem, linked at the end. If I had to estimate a number, it's marked with a *. Each case also gets a write-up that names the company, with the timeline, exact quotes and sources.

I answer every email. Write to milan@briefcasestudy.com, or start with every case so far.
