01 — about me

The Story

As a PC gamer growing up, I wasn't just playing games — I was pulling machines apart and figuring out how everything worked. That obsession with how computers tick never left me. It just evolved.

Today I'm a Cloud & DevOps Engineer based in Melbourne, with 2+ years of hands-on experience designing, deploying, and automating cloud infrastructure on AWS. I specialise in building resilient, scalable systems using Infrastructure-as-Code, CI/CD pipelines, and cloud-native AWS services — with a strong security-first mindset.

I don't just keep the lights on. I eliminate manual deployments, build infrastructure engineering teams' trust at scale, and I've cut deployment time by 60% in production environments.

What I've Built

PROJECT_001
Production AWS Infrastructure — Zero Console Challenge
Built a complete production-grade AWS environment using 100% Terraform — never touching the AWS console once. Designed for high availability across two availability zones with security-first architecture.
VPC with public + private subnets across 2 AZs
ALB routing to EC2 in private subnets — zero direct internet access
S3 buckets with encryption, no public access
IAM roles with strict least-privilege policies
Remote state management: S3 + DynamoDB locking
100% Infrastructure as Code — fully reproducible
Terraform AWS VPC EC2 AWS ALB AWS S3 AWS IAM
Challenge Completed

PROJECT_002
CI/CD Pipeline — Auto Deploy to AWS
GitHub Actions pipeline that automatically deploys to the Terraform infrastructure on every git push. Proving end-to-end ownership: build the infra, then automate the delivery.
Automated Terraform plan on every pull request
Automatic infrastructure deployment to the development environment after merge
Application deployment triggered when app/ changes are detected
Manual approval workflow for staging and production deployments
Multi-environment pipeline using GitHub Actions and Terraform
GitHub Actions EC2 Terraform OpenID Connect (OIDC) AWS IAM
Challenge Completed

PROJECT_003
Docker Containerization — Multi-Stage Builds
Containerized full-stack Node.js application with production-optimized multi-stage Docker builds. Expecting to reduce image size by 78% and deployment time significantly through efficient layering and caching strategies.
Multi-stage Dockerfile — separate build and runtime stages
Alpine Linux base — minimal image footprint (24MB final)
Docker Compose for local dev environment
Image scanning with Trivy — zero high/critical vulnerabilities
Container registry push to ECR on CI/CD success
Health checks and graceful shutdown handling
Docker Docker Compose AWS ECR Node.js Trivy GitHub Actions
