Service Mesh: When and Why
Sidecar proxies for traffic management, mTLS, observability, and resilience — what a service mesh actually buys you, and when the operational cost is worth it.
Helm Charts: Packaging K8s Applications
Kubernetes's package manager — chart structure, values.yaml, Go templates, dependencies, and release management (install, upgrade, rollback) for real deployments.
Container Registry Best Practices
Store, scan, and distribute container images — immutable tags, vulnerability scanning policies, geo-replication, and retention rules that keep a registry trustworthy.
Alerting: Signal vs Noise
Actionable alerts, on-call rotations, and incident response — alert rules, severity, routing, and the fatigue-prevention discipline that keeps on-call sane.
Production Monitoring: The Four Golden Signals and the SLO Stack
Latency, traffic, errors, and saturation — the four golden signals — plus SLIs, SLOs, error budgets, and the alerting philosophy that prevents alert fatigue.
Branching Strategies: Trunk-Based Development vs GitFlow in 2026
Trunk-based development, feature flags, short-lived branches, GitFlow trade-offs, and why high-performing teams converge on committing to main.
CI/CD Pipeline Design: Fast Feedback, Quality Gates, and DORA Metrics
Trunk-based development, parallel testing, deployment gates, feature flags, and designing pipelines that keep deployment frequency high and failure rate low.
Kubernetes Deployments: Rolling Updates, Resource Limits, and HPA
Deployment strategies, readiness and liveness probes, resource requests and limits, Horizontal Pod Autoscaler, and PodDisruptionBudgets for zero-downtime releases.
Docker for Production: Multi-Stage Builds, Security, and Compose
Multi-stage builds that cut image size by 80%, non-root users, read-only filesystems, health checks, and Compose patterns for local development parity.
GitHub Actions in Production: Workflows, OIDC, and Reusable Patterns
Triggers, matrix builds, reusable workflows, composite actions, OIDC cloud authentication, and the patterns that keep CI pipelines fast and secure.
