CI/CD Pipeline (GitHub Actions)
End-to-end deployment automation: on every PR lint, type check, unit tests, integration tests (Testcontainers), security scan (Trivy, Snyk), build Docker image. On merge to main deploy to staging, smoke tests, manual approval for production, rolling deployment with CloudWatch alarm-based automatic rollback.
Infrastructure Automation (IaC)
Beyond CI/CD automating all infrastructure operations: AMI patching pipeline (AWS Systems Manager Patch Manager), database backup verification (automated restore-and-check weekly), SSL certificate monitoring (alert 30 days before expiration), DNS/CDN invalidation automation, scheduled maintenance windows with pre/post health checks.
Monitoring & Alerting
Production observability: CloudWatch dashboards (app + infrastructure metrics), Grafana (custom Prometheus dashboards P50/P95/P99 latency, error rate, throughput, queue depth), PagerDuty (on-call rotation, alert escalation), Sentry (error tracking exception grouping, release attribution), uptime monitoring (external availability checks).
SRE Practices
Site Reliability Engineering for mature orgs: SLO definition (99.9% availability, P95 latency <200ms), error budget (allowed downtime per month teams move fast when healthy, slow when depleted), toil reduction (identify and automate repetitive manual tasks), blameless post-mortems (five whys root cause, action items to completion).
On-Call & Incident Response
Operational resilience: runbook documentation (step-by-step recovery for every critical failure), alert fatigue reduction (alert on genuinely actionable conditions), war room process (incident commander, communication lead, technical lead pre-defined templates), post-incident review (P0/P1 incidents, findings shared with full engineering team).
