• Designed and operated a production-style Kubernetes platform on Azure AKS for a containerized microservices application (React frontend, 3 Node/Express services, MongoDB), with images in Azure Container Registry.
• Built CI/CD foundations with GitHub Actions and passwordless Azure OIDC authentication — reducing reliance on long-lived cloud credentials — plus Kubernetes Ingress, DNS and TLS/HTTPS for externally accessible REST APIs.
• Implemented observability with Prometheus, Grafana, Loki and Grafana Alloy across infrastructure, application and security events.
• Integrated a Cowrie SSH/Telnet honeypot with an AI-assisted operational interface that retrieves platform health and recent security events.
• Performed Trivy vulnerability scanning — surfaced real HIGH/CRITICAL findings in application images.
• Diagnosed deployment failures involving Kubernetes networking, authentication, MongoDB connectivity, application dependencies and resource configuration, using kubectl, logs, events and Linux tooling.

"Instead of manually going through logs, the goal was to ask ‘are my pods healthy?’ or ‘what commands did the attacker execute?’ — the assistant routes the request to an approved operation and returns a human-readable answer, never raw shell or database access."

• Provisioned AWS infrastructure with Terraform, including VPC, public/private subnets, route tables, NAT Gateway, security groups, EC2, S3 remote state and DynamoDB state locking.
• Deployed a Docker-based microservices voting application (Python Flask, Redis, .NET worker, PostgreSQL, Node.js) to Amazon EKS.
• Configured NGINX Ingress, Route 53 DNS, cert-manager HTTPS and Horizontal Pod Autoscaling.
• Troubleshot DNS, TLS, networking and CPU resource-request issues with kubectl and Linux tooling.
• Load-tested the Horizontal Pod Autoscaler against the voting traffic path.
