Key Project Objectives

• Cloud Foundation & Landing Zone: Deploy target hybrid network architectures, establishing a secure Landing Zone and hybrid Data/AI platforms on AWS.
• Security, Compliance & Governance: Operationalize on-prem tokenization (achieving zero raw PII in the cloud), resolve policy blockers to include AWS in the ISMS, and establish a Cloud Center of Excellence (CCoE) to govern Cloud adoption.
• AI Chatbot & Voicebot Design & Implementation: Develop and operationalize a flagship Customer Care Chatbot and Voicebot as the first hybrid-setup consumer.

Key Responsibilities

• Design, provision, and maintain production-grade Amazon EKS clusters across AWS cloud and on-premises environments using EKS Hybrid Nodes with Cilium VXLAN CNI overlay networking.
• Implement dynamic node autoscaling and OS lifecycle management using Karpenter and immutable Bottlerocket node images across cloud and hybrid compute nodes.
• Configure and manage EMR-on-EKS platform runtimes to execute distributed Big Data and PySpark batch/streaming analytics workloads.
• Provision, optimize, and manage specialized GPU node pools (NVIDIA A100/L40S / EC2 GPU instances) for Azerbaijani SLM/LLM model training, fine-tuning, and low-latency speech inference (ASR / TTS voicebot pipelines).
• Implement automated GitOps continuous deployment workflows using Argo CD and Helm charts for all Kubernetes platform components and application workloads.
• Enforce cluster security, governance, and compliance using Kubernetes admission controllers and policy engines (e.g., OPA / Kyverno) alongside fine-grained Workload Identity (IRSA / Pod Identities).
• Build and maintain Infrastructure-as-Code (IaC) templates using Terraform and AWS CDK integrated into GitLab CI/CD pipelines for repeatable cluster lifecycle management.
• Implement container microsegmentation, network security policies, and split-horizon DNS resolution across hybrid VPCs and on-premises substrates.
• Integrate platform logging, metrics, and trace telemetry with Amazon CloudWatch and central on-premises Splunk / SOC SIEM ingestion pipelines.
