Automated EC2 cost optimization using Lambda functions (start/stop automation, tagging strategy, Slack notifications).
Improved resource organization by effectively using tags and creating Resource Groups for better visibility and management.
Enhanced access control skills by applying IAM policies tied to resource tags and validating permissions across multiple AWS Regions.
Strengthened IAM governance through implementing permission boundaries to enforce strict user limitations.
Gained strong hands-on experience with AWS KMS encryption, S3 secure storage, CloudTrail auditing, and Athena log analysis.
