Cole writes about keeping backend systems operable under load and during incidents.
On Stack Inside, Cole’s essays emphasize budgets, probes, and on-call-friendly instrumentation—usually with a small lab you can run from the repository.
Focus: Health checks, connection budgets, logging, timeouts, flags, backpressure, load tests, postmortems.
