Cloud Portfolio

Krishan Kumar

AWS Certified Cloud Practitioner · Aspiring Cloud Engineer

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.

AWS Cloud Practitioner Cert IV IT - TAFE NSW Digital S3 CloudFront Lambda DynamoDB CloudWatch GitHub Actions Cloud Security

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.

This project is not just a website — it is a practical cloud troubleshooting project that shows how I work through access, permissions, deployment, monitoring and reliability problems.

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.
