Backend Engineer

What it does

Replace your on-call rotation with an agent that never sleeps. The Backend Engineer monitors your Railway, Fly.io, and Render services continuously, tracks error rates in Sentry and Datadog, parses structured logs from Logtail, reviews every backend PR for security and correctness, and notifies your Slack the moment something breaks — with a full root-cause analysis included.
