📂 Projects & Home Lab

Serverless Static Web Hosting on AWS

Deployed a scalable, high-performance static website using a serverless architecture on AWS. Configured Amazon S3 for secure object storage and CloudFront (CDN) for global content delivery. Managed DNS routing via Route 53 and implemented SSL/TLS security using ACM. The solution focused on high availability, low latency, and cost optimization.

Stack: AWS (S3, CloudFront, Route 53, ACM)

K8s Deployment on AWS

Deployment of a containerized web application to an AWS-provisioned Kubernetes cluster. The project involved using S3 for cluster state persistence and configuring Route 53 for custom DNS service exposure, bypassing standard Load Balancers to understand underlying networking.

Stack: AWS, Kubernetes, Docker, Route53

Automated Provisioning with Ansible & Terraform

End-to-end automation pipeline. Used Terraform to provision AWS EC2 infrastructure and Ansible playbooks to configure the environment and install Docker Engine. Focused on mastering the Infrastructure as Code (IaC) lifecycle.

Stack: Terraform, Ansible, AWS EC2, Linux
