I’m transitioning into cloud and IT through hands-on AWS projects, Cert IV Information Technology study, and practical troubleshooting experience. This portfolio demonstrates cloud hosting, serverless backend logic, monitoring, CI/CD, security hardening and documentation.
Featured AWS Project
Cloud Resume + Live Operations Dashboard — a serverless AWS portfolio project built with S3, CloudFront, Route 53, ACM, API Gateway, Lambda, DynamoDB, CloudWatch and GitHub Actions.
Secure Static Hosting
Hosted the portfolio using S3 and CloudFront, with HTTPS through ACM and DNS routing through Route 53.
Private S3 Access
Worked with CloudFront Origin Access Control to keep the S3 bucket private while serving content securely.
Serverless Visitor Counter
Built a visitor counter using API Gateway, Lambda and DynamoDB to track total and unique visitor activity.
CloudWatch Dashboard
Added monitoring visibility with CloudWatch logs, metrics and a live dashboard for visitor statistics.
CI/CD Deployment
Configured GitHub Actions to deploy updates to S3 and invalidate CloudFront after changes are pushed.
Security and Secrets
Used GitHub Secrets for deployment credentials and moved Git access away from password-based authentication.
Troubleshooting Wins
This project gave me real practice debugging cloud issues across frontend, backend, deployment and AWS service layers.
403 AccessDenied
Investigated missing files, S3 access, bucket policy behaviour and CloudFront origin configuration.
API / Lambda Errors
Worked through API Gateway and Lambda issues using testing, logs and response checking.
DynamoDB Issues
Handled update expression problems, including reserved keyword behaviour in DynamoDB.
GitHub Actions Failure
Debugged a workflow deployment issue caused by a broken S3 sync exclude line.
CloudFront Cache
Used invalidations to solve stale content problems after deployment changes.
CSP / Browser Security
Worked through security header and Content Security Policy issues affecting scripts, styles and API calls.
Current Skills Focus
Cloud and Infrastructure
- AWS fundamentals and cloud architecture basics
- S3, CloudFront, Route 53, ACM and Origin Access Control
- Serverless basics with API Gateway, Lambda and DynamoDB
- Monitoring with CloudWatch logs, metrics and dashboards
Support and DevOps
- Incident-style troubleshooting and documentation
- Git, GitHub and SSH-based authentication
- GitHub Actions CI/CD and deployment debugging
- AWS CLI, cache invalidations and deployment verification
Learning Path
I’m currently studying Certificate IV in Information Technology through TAFE NSW Digital while building practical cloud projects to strengthen my AWS, networking, Linux, security and troubleshooting skills.
This portfolio is actively being improved as part of my transition into cloud engineering.
