Sre Expert

This gives you working SRE frameworks for the stuff that actually matters: SLO tracking with error budget calculations, incident management with proper severity levels and timelines, and the kind of structured approaches that keep production stable. The code is practical, like the SLOTracker that calculates compliance windows and the IncidentManager that handles the whole lifecycle from detection to post-mortem. It's built for teams moving past ad-hoc firefighting into actual reliability engineering, where you need to quantify uptime, manage on-call sanely, and learn from failures. The Python examples are complete enough to adapt rather than rewrite from scratch.
