01 / ABOUT

Cloud thinking.
Business impact.

I am an AWS-focused cloud professional specializing in cloud architecture, infrastructure design, deployment automation and cost optimization. I am passionate about building secure, scalable and reliable cloud solutions that address real business needs. My interests include AWS infrastructure migration, CI/CD pipelines, containerization, cloud security and operational efficiency. Through practical projects, I aim to demonstrate sound architectural decisions, automation, and cost-conscious infrastructure design.

My portfolio explores infrastructure architecture, deployment automation, migration planning and cost-conscious design. I aim to document not just what a solution uses, but why each architectural decision makes sense.

Explore the projects below as they move from reference designs into tested, documented implementations.

AWS Three-Tier Architecture Foundation

Designed a six-subnet VPC across two Availability Zones and deployed an EC2-hosted HTTP test application with systemd and Session Manager. Validated public access and temporary ALB routing, investigated target health, and removed the ALB after testing to control costs. Private application deployment, Auto Scaling and RDS remain future work.

DEVOPS & AUTOMATIONImplemented · CI/CD verified

Containerized AWS CI/CD Pipeline

Built and verified a GitHub Actions pipeline for a Node.js/Express app. The workflow installs dependencies, runs three automated tests, builds a Docker image, and publishes latest and commit-SHA tags to GitHub Container Registry and private Amazon ECR. GitHub Actions authenticates to AWS using OIDC and a least-privilege IAM role, without long-lived AWS access keys. The project intentionally stops at image publishing; ECS/Fargate deployment is future work to keep costs controlled.
