I'm Diego, a Senior SRE based in Barcelona. I've spent the last eight years on-call for teams ranging from four people to four hundred, and most of what I write here is some version of "here is the thing I wish somebody had told me earlier."

I care about boring reliability. The unglamorous checks. The runbook you can read at 3am with one eye open. Error budgets as a negotiation tool, not a scoreboard. Postmortems that change something.

On the side I run srereview.com — lightweight SLO and on-call reviews for small engineering teams. If that sounds useful, it probably is.

The fastest way to reach me is email.
