25 Years at Scale

At year five you think you understand scale. At year twenty-five you realize scale isn't a technical problem.

I've run teams that kept healthcare platforms alive through the night. Architected systems that quietly processed hundreds of millions of transactions without anyone noticing, which is the point. Built the infrastructure behind products used by people who never once thought about the pipes underneath.

The technical part gets easier. Not simpler, easier. You've seen the failure modes. You've felt the 3am pages. You've refactored the same class of mistake in six different languages across four decades of tooling.

What gets harder is the human layer. Communicating tradeoffs to executives who want certainty. Protecting engineers from organizational chaos. Knowing when to say the system is fine and the problem is the process.

The real skill isn't distributed systems. It's translation, between business reality and technical truth, between what's being asked for and what's actually needed.

25 years in, that's the work I want to keep doing. Preferably on things I own.
