• Performance troubleshooting (CPU/memory profiling, latency analysis, concurrency tuning).
• Infrastructure-as-code (Terraform modules, state management, policy enforcement).
• Observability stack (Prometheus, Grafana, OpenTelemetry, alert tuning).
• Strong Python (packages, virtual environments, dependency management, performance profiling).
• Strong Jenkins (shared libraries, pipelines-as-code) & Tekton (Tasks, Pipelines, Triggers).
• Containerization (Docker image optimization, multi-stage builds, runtime security).
