PORTFOLIO SHOWCASE
SELECTED PROJECTS
CLOUD INFRASTRUCTURE
AWS Idle Resource Checker
A Python tool that scans EC2 instances, reads CPU utilisation from CloudWatch, flags idle servers, and estimates what keeping them running costs per month. Built and tested in a locked-down AWS Free Plan lab.
HIGHLIGHTS
- 01Set up an AWS Free Plan account with MFA on the root user, a separate IAM user for daily work, and an AWS Budgets alert as a cost safety net
- 02Launched three EC2 test instances in Singapore — two left idle and one running continuous CPU load — all with no public IP, no SSH, and no key pairs
- 03Connected from the laptop through the AWS CLI, keeping access keys in the local AWS config so no credentials appear in code or in the repository
