CloudOps Kubernetes Observability Mesh & GitOps
Candidate Portfolio Role: DevOps & Site Reliability Contributor
Declarative GitOps deployment pipeline using ArgoCD, OpenTelemetry distributed tracing across microservices, Prometheus SLA monitoring, and AWS EKS multi-AZ clusters with auto-rollback triggers.
Industry Problem Statement & Production Scope
Distributed microservices in cloud environments suffer from configuration drift, opaque cascading failures, and high MTTR (Mean Time to Recovery) without declarative infrastructure-as-code and unified telemetry.
