“What was the moment this product clicked?” —
A backend, frontend, or full-stack developer at a product company for whom Sentry is the first place they look when something goes wrong in production. They didn't set Sentry up — it was already there when they joined — but they've learned to read its output. They've been paged because of a Sentry alert. They've traced a production incident back to a specific line using Sentry's stack traces. They've also spent 40 minutes investigating a Sentry error that turned out to be a bot making malformed requests. They've learned to filter.

What do they produce? —
It's Wednesday afternoon. A Sentry alert fires: `TypeError: Cannot read properties of undefined`. The error count is 47 in the last hour, up from 0. They open Sentry. The stack trace points to a third-party library boundary — not their code. They click through to the breadcrumbs: three API calls, then a state update, then the error. The user context shows it's only happening for users on a specific plan. That's enough. They know what changed. The deploy that caused this went out 90 minutes ago. They're writing the fix.
Uses Sentry at work — rarely sets it up, always uses it. Has Sentry integrated for at least one production service. Reviews Sentry alerts in email, Slack, or PagerDuty. Has source maps configured (or has been frustrated that they're not). Uses Sentry's issue assignment to route errors to the right engineer. Has set up alert rules for error rate thresholds. Checks Sentry's performance tab occasionally. Wishes the performance tab were more useful. Has muted at least 5 recurring errors they've decided not to fix yet and feel mild guilt about.
Pairs with `pagerduty-primary-user` for the error detection-to-incident response workflow. Contrast with `datadog-primary-user` for the error monitoring vs. full observability platform comparison. Use with `vercel-primary-user` for frontend developers deploying on Vercel with Sentry monitoring.
