Cloud Infrastructure

Deploying scalable, self-healing systems with automated synchronization.

  • ArgoCD GitOps inside AWS EKS

    Implemented a full GitOps workflow for production workloads.

    • Tech Stack: ArgoCD, AWS EKS, GitLab CI, Helm
    • Impact: achieved a "Single Source of Truth" for cluster configuration and automated image updates via ArgoCD Image Updater.

    Details

  • AWS EKS Infrastructure as Code

    Provisioned a high-availability Kubernetes cluster from scratch using Terraform.

    • Tech Stack: Terraform, AWS EKS, VPC CNI, IAM Roles
    • Impact: automated node group scaling and centralized logging with CloudWatch, ensuring >99.9% uptime.

DevSecOps & CI/CD

Shifting security left and optimizing delivery pipelines.

  • Enterprise DevSecOps Pipeline

    Integrated automated security scanning into massive-scale GitLab CI/CD pipelines.

    • Tech Stack: GitLab, Trivy, Docker, Bash
    • Impact: automatically detected vulnerabilities in container images before deployment, drastically reducing manual audit time.

    Details

  • Cost-Optimized GitLab Runners

    Migrated runner infrastructure to AWS EC2 Spot Instances to slash operational costs.

    • Tech Stack: AWS Auto Scaling, Spot Instances, Ansible
    • Impact: ~60-70% reduction in CI/CD infrastructure costs without sacrificing pipeline performance.

Observability & Cloud Migration

Ensuring system reliability through advanced monitoring and containerization.

  • Centralized Monitoring Stack

    Deployed a unified observability platform for multi-environment resources.

    • Tech Stack: Prometheus, Grafana, Loki, Alertmanager
    • Impact: provided real-time visibility into infrastructure health and reduced MTTR through proactive Slack/Email alerts.

    Details

  • Cloud Migration & Dockerization

    Migrated legacy on-premises workloads to containerized AWS cloud environments.

    • Tech Stack: Docker, AWS (EC2, S3, RDS), Nginx
    • Impact: simplified maintenance and improved response times by ~40% through modernized orchestration.
