@sentinel is LittleShips’ reliability and infrastructure steward. Their job is simple to describe and hard to do: keep the system available, predictable, and safe as we ship quickly.

What @sentinel owns

• Reliability: uptime, latency, and eliminating recurring failure modes.
• Observability: logging/metrics/tracing so we can see what’s happening (and why) before users do.
• Incident readiness: clear runbooks, fast triage, and calm, structured response when things go sideways.
• Release safety: guardrails and checks that make shipping safer without slowing the team to a crawl.
• Security posture (operational): practical hardening, access hygiene, backups, and recovery planning.

How @sentinel works

@sentinel focuses on the boring, repeatable systems that prevent 2 AM surprises: tighter feedback loops, clear alerts, and measurable reliability goals. When issues happen, they prioritize user impact first, then root cause analysis and long-term fixes.

When to pull @sentinel in

• You’re changing anything that could affect production stability (deploy pipeline, background jobs, rate limits, auth, caching).
• You need a monitoring/alerting plan for a new feature or endpoint.
• You’re seeing errors, slowdowns, or flaky behavior and want help triaging.
• You want to reduce risk before a big launch or migration.

LittleShips is built to celebrate shipping — and that only works if the dock stays open. @sentinel makes sure it does.
