SLIs, SLOs, and error budgets
Define what good looks like for users so ship-versus-harden stops being politics.
Site Reliability Engineering
Reliability as a product feature: service-level indicators, OpenTelemetry monitoring, and less repetitive firefighting so incidents have a defined path and on-call has evidence.
Founder-led. Fixed scope. Ownership left with your team.
The Problem We Solve
Reliability is often an operations afterthought: more alerts, more weekend pages. Without SLIs, error budgets, and monitoring that maps to user impact, teams optimise the wrong things. We put numbers on user impact, instrument critical paths, and turn recurring firefights into permanent fixes.
Who This Is For
- Teams shipping features that fail quietly under load before monitoring notices.
- Leaders who need SLIs and error budgets, not green dashboards while users suffer.
- On-call groups drowning in alerts that do not map from symptom to code.
What We Deliver
Reliability work in the paths that hurt, not a generic SRE playbook on a shelf.
OpenTelemetry monitoring
Traces, metrics, and logs that connect a user symptom to a code path.
Less repetitive firefighting
Turn recurring incidents into automated checks and permanent guardrails.
Performance under real load
Find bottlenecks demos miss: pools, N+1 queries, cold starts, noisy neighbours.
How We Work
Embed SRE where it pays first: critical paths and recovery engagements, then expand. Week one: map user-critical paths, alerts, and incident patterns; agree first indicators and monitoring gaps. You leave with a prioritised reliability backlog and early telemetry on the paths that hurt most.
What You Leave With
- A reliability baseline the business can understand, in user impact not raw server metrics.
- Faster diagnosis and fewer pages for the same class of incident.
- Engineering time reclaimed from firefighting and returned to product work.
