This repository showcases real DevOps automation in a hybrid infrastructure setup, combining Infrastructure as Code, automated provisioning pipelines, configuration management, and observability — all tied together with deployable code.
🎯 Designed for hiring managers, engineers, and teams evaluating real-world DevOps skill sets
| Capability | Tech Used |
|---|---|
| Infrastructure Provisioning | Terraform (VPC, EC2, S3, RDS) |
| Configuration Management | Ansible (Nginx, Prometheus, Grafana) |
| Dynamic Inventory | Ansible + Boto3 (EC2 sync) |
| IaC Automation Pipeline | GitLab CI/CD |
| Monitoring & Visualization | Prometheus + Grafana |
| Documentation | Markdown + Diagrams |

This lab emulates a production-like flow:
- Code pushed → GitLab CI pipeline triggers
- Terraform provisions VPC, EC2, S3, and RDS
- Ansible installs Nginx, Prometheus, Grafana on EC2
- Dynamic Inventory auto-syncs EC2 IPs
| Tool | Output Snapshot |
|---|---|
| Terraform | ✅ Applied Successfully (see outputs.tf) |
| Ansible | ✅ Configured Nginx, Prometheus, Grafana |
| Grafana UI |  |

This project was built during a personal reset period — not to learn DevOps, but to rebuild it from first principles.
I didn't just write Terraform, Ansible, and CI pipelines — I verified each commit by applying it on real infrastructure.
It's my way of proving that even outside of a job, I never stopped building.
