I build and automate AWS infrastructure and production-style cloud platforms with a focus on reliability, observability, secure deployment, and operational troubleshooting.
My projects demonstrate hands-on work with Terraform, AWS networking, ECS, Docker, CI/CD, CloudWatch, IAM, GitHub Actions, Linux, and infrastructure automation.
I focus not only on building systems, but on understanding how they deploy, scale, fail, recover, and operate in production.
- ☁️ Building production-style infrastructure on AWS
- 🏗️ Developing reusable infrastructure with Terraform and Infrastructure as Code
- ⚙️ Automating deployments through GitHub Actions and CI/CD
- 🐳 Deploying containerized workloads with Docker, Amazon ECR, and Amazon ECS
- 📊 Building observability with CloudWatch dashboards, metrics, alarms, and SNS
- 🌐 Working with VPCs, subnets, routing, load balancing, DNS, and security groups

This project explores:
- What happens when an instance fails?
- What happens when an Availability Zone fails?
- Where are the potential single points of failure?
- What happens at 10× traffic?
- How should infrastructure health be monitored?
- How should an outage be investigated?
- How can the architecture recover from failure?
Engineering Lifecycle
Architecture → Automation → Security → Availability → Scaling → Monitoring → Troubleshooting
I approach infrastructure as an operational system, not simply a collection of AWS resources.
Create repeatable infrastructure using Terraform and Infrastructure as Code.
Apply IAM least privilege, network isolation, and secure authentication.
Reduce repetitive manual operations using CI/CD, Terraform, and scripting.
Use repeatable deployment pipelines and versioned artifacts.
Collect metrics, logs, health signals, and alarms.
Trace problems through infrastructure dependencies to isolate the root cause.
Restore service and verify that the system has returned to a healthy state.
Use failures and operational data to improve automation, architecture, monitoring, and reliability.
