Thanks, Diego. Tell me about a service you took to production and what broke first.
A payments API. The retry logic broke under load.
How did you find it, and what did you change?
Latency alerts. We added idempotency keys and a backoff.

Context

The starting point

A Silicon Valley technology company screens every applicant by phone before a recruiter sees the profile. Its team ran about 1,000 calls a month.

Every hiring push outran that capacity, so the queue grew instead of the shortlist.
