Modularized multi - cloud infrastructure across aws and oci using terraform, standardizing vpc network topologies, security groups, and iam policies across development and production environments. refactored gitlab ci/cd pipelines by introducing dependency caching, isolated test stages, and automated container image linting, reducing build times from 16 minutes to under 4 minutes. migrated multi - service web applications from standalone docker compose setups to kubernetes, configuring argocd to enforce declarative gitops synchronization and enable rolling updates without service downtime. integrated prometheus and grafana dashboards for cluster and host metrics, configuring automated alert thresholds for memory exhaustion and crash loops, which decreased incident triage time by 40 . automated baseline server provisioning and routine maintenance across ubuntu nodes with ansible playbooks, eliminating configuration drift across hosts. configured edge ingress and reverse proxying via nginx and caddy with automated let's encrypt ssl/tls renewals, maintaining high availability for external endpoints. featured projects gitops cloud infrastructure kubernetes lab
