Site Reliability Engineering for high‑stakes systems
Practical reliability for fast‑moving teams. I help you ship faster and sleep better through well‑designed SLOs, observability, and incident response.
Fewer incidents
Stabilize core services with pragmatic guardrails, runbooks, and chaos‑safe changes.
Faster recovery
On‑call you can trust: clean escalation paths, actionable alerts, and blameless postmortems.
Predictable velocity
SLOs and golden signals drive product decisions without slowing delivery.
Services
Reliability Strategy
Define service tiering, SLOs, and error budgets. Establish change policy and reliability guardrails.
Observability
Metrics, logs, and traces that matter. Alerting tuned for signal over noise.
Incident Management
IM playbooks, roles, post‑incident reviews, and tooling integrations that reduce MTTR.
Performance & Resilience
Capacity planning, load testing, fault injection, and autoscaling strategies.
Platform & Cloud
IaC reviews, multi‑AZ patterns, safe deployments (blue/green, canary), and cost controls.
Advisory & Fractional SRE
Hands‑on guidance or part‑time leadership to bootstrap or level‑up your SRE practice.
