Project Overview:
The project involved modernizing and maintaining a large-scale AWS environment across multiple VPCs, focusing on infrastructure security, compliance, cost optimization, and patch management. The objective was to ensure full automation of routine operational tasks, increase compliance visibility, and support application teams with a stable and secure cloud foundation.
Key Responsibilities:
Managed 200+ EC2 instances across production and non-production environments running on RHEL 7.9 8.10 after a successful OS upgrade and validation.
Automated weekly patching and compliance reporting through AWS Systems Manager (SSM), CloudWatch, and Lambda functions to reduce manual overhead by 70%.
Developed Lambda-based inventory scripts (Python/Boto3) to extract metadata for WorkSpaces, EC2, and IAM — capturing bundle type, owner, creation date, and compliance status.
Configured and optimized CloudWatch alarms, EventBridge rules, and SNS notifications for proactive incident detection.
Conducted IAM access reviews, group policy audits, and least-privilege enforcement in alignment with CIS benchmarks.
Collaborated with DevOps and Security teams to integrate AWS Config, GuardDuty, and Security Hub for unified compliance visibility.
Worked with CloudFormation and CDK templates for infrastructure provisioning and environment consistency.
Supported cost optimization through EBS right-sizing, S3 lifecycle policies, and unused resource cleanup using automated scripts.
Provided regular compliance and patching dashboards to management and auditors for weekly reviews.
Tools & Technologies:
AWS Services: EC2, S3, RDS, Lambda, CloudWatch, SSM, CloudFormation, Config, SNS, GuardDuty, Security Hub
Languages/Scripts: Python (Boto3), Bash, PowerShell
Monitoring & Reporting: CloudWatch, QuickSight, ELK Stack, Cost Explorer.
Achievements:
Reduced monthly compliance deviations by over 40% through automated reporting and patch scheduling.
Achieved 100% visibility of EC2/WorkSpaces assets with metadata tagging and automated tracking.
Improved incident response time by 60% with centralized CloudWatch + SNS alerting integration.
Recognized by the client for exceptional AWS cost optimization and proactive issue mitigation
