Designed and deployed a production-grade private cloud from scratch using Infrastructure as Code (Kayobe + Ansible) — compute, networking, distributed storage, fully automated, zero managed cloud dependency.
CaaS Self-Service Portal enabling engineers to provision Kubernetes clusters on private cloud via Cluster API — full lifecycle management (create, scale, upgrade, decommission), cutting provisioning time from days to minutes.
Multi-cluster GitOps with ArgoCD Fleet managing dev/staging/prod environments from a single Git source of truth — zero configuration drift, instant rollback capability across all clusters.
vCluster tenant isolation — Kubernetes-in-Kubernetes virtual clusters for engineering teams, enabling self-service namespaces and reducing platform team toil by ~50%.
SIEM/SOC automation platform with automated threat detection, rule tuning, alerting pipelines, and incident response playbooks covering the full infrastructure stack.
SLO/SLA-driven observability stack (Prometheus + Grafana + Loki + OpenTelemetry) — reduced MTTD by ~40% and major incidents by 35%.
End-to-end CI/CD automation (GitHub Actions + Terraform + ArgoCD) across 10+ microservices — ~40% reduction in manual operations and deployment failures.
Security hardening at every layer — IAM least-privilege, VPC micro-segmentation, Calico network policy enforcement, Harbor image scanning, and automated vulnerability reporting.
Service Mesh implementation with Istio — mTLS between all services, traffic shaping, circuit breaking, and distributed tracing via OpenTelemetry.
