Systems design for distributed services (scalability, resilience, failure handling)
Cloud infrastructure architecture (AWS/Azure/GCP fundamentals, networking, identity, storage)
Infrastructure as Code (e.g., Terraform) and repeatable environment builds
Container platforms and orchestration (commonly Kubernetes) and service deployment patterns
CI/CD pipeline design (automated testing, safe releases, rollbacks)
Observability (metrics, logs, tracing) and practical on-call/incident leadership
Security by design (least privilege access, secrets handling, threat-aware architecture)
Cost and performance optimization (capacity planning, right-sizing, efficiency tradeoffs)
Influence without authority: setting standards, driving adoption, aligning stakeholders
Clear technical writing and documentation for self-service platforms
