Architected and deployed a production-grade 10-service AI microservices platform on AWS EKS using ArgoCD GitOps with 7-wave ordered sync and zero-downtime deployments.

AWS EKS ArgoCD OpenAI GPT-4o Kustomize Helm Prometheus Grafana cert-manager IRSA OIDC

✅ Key Highlights:

• 🔐 Implemented IRSA + OIDC/STS token exchange — eliminated all static AWS credentials
• 🧠 Integrated GPT-4o tool-calling agent querying live cluster, payment & product services
• 📈 HPA on API gateway (2–10 replicas at 70% CPU) with Kustomize overlay for EKS prod / microk8s dev
• 🔒 Automated TLS via cert-manager + Let's Encrypt ACME HTTP-01 on Nginx ingress
• 📊 Prometheus ServiceMonitor with custom alerting rules: ServiceDown, HighCPU > 80%, HighMemory > 85%
