Experience
A GitOps Workflow Using Argo CD and Terraform to Reduce Deployment Errors
As a DevOps engineer at Apple, I designed and implemented a GitOps-based deployment workflow for our mobile app infrastructure using Argo CD and Kustomize, supporting development, test, stage, and production environments on Amazon EKS.
I provisioned and managed the infrastructure with Terraform using Terragrunt to eliminate code duplication across environments and ensure consistent deployments.
Applications were containerized using Docker and deployed via Kubernetes, with Argo CD ensuring continuous synchronization between Git and the live environment.
For observability, I integrated Datadog for real-time performance metrics, Prometheus for custom monitoring and alerting, and Splunk for centralized log analysis. I also configured PagerDuty for on-call management and automated incident escalations.
RESULTS
Reduced deployment errors, improved infrastructure consistency, and significantly accelerated rollout cycles through automation and GitOps best practices.

CI/CD Pipeline for Tier 3 AWS Web App
As a DevOps engineer at Delta Air Lines, I built a full CI/CD pipeline for a tier 3 AWS web app, including the front end, back end, and database. I utilized Terraform to provision infrastructure, including VPCs, Amazon EC2 instances, and Amazon RDS.
I used GitHub Actions to automate testing, build Docker images, and deploy to appropriate environments, such as development, stage, and production. I also handled secure secrets management and environment-specific variables.
RESULTS
The pipeline improved release speed by approximately 40% and reduced manual steps, providing a more secure and reliable deployment workflow.

Datadog Monitoring and Argo CD for EKS/GKE Clusters
As a site reliability engineer at 2K Games, I established observability for Kubernetes workloads running on Amazon EKS and GKE. I deployed Datadog Agents and Operators using Argo CD by structuring them as GitOps applications:
• Agent YAML (kind: Datadog) was managed in an agent/folder.
• Operator YAMLs were in an operator/folder with values.yaml to define properties like fullnameOverride: datadog-operator.
This approach ensured consistent agent deployment and version control across clusters.
Also, I created custom Datadog dashboards and configured monitors for CPU, memory, request rates, and errors. Alerts were routed to PagerDuty for production and Slack for non-production.
Argo CD also managed app deployments, ensuring sync between Git and cluster state, reducing drift, and enabling fast rollbacks.
RESULTS
As a result, I improved visibility and enabled faster incident detection and safer deployments.
