Siddharth Rao

• Assisted senior engineers with patching 10 EC2 instances across dev and staging environments following a structured runbook; zero missed patches across a 6-week patching cycle.
• Wrote a Bash script to automate log archival from EC2 to S3 (triggered via cron), eliminating a 2-hour weekly manual task that had been performed by a senior engineer.
• Helped configure CloudWatch alarms for CPU, memory, and disk thresholds on 8 EC2 instances; provided first monitoring coverage for a legacy application previously managed with no automated alerting.
• Documented 6 operational runbooks for routine tasks including backup verification, EC2 restart procedures, and IAM access review steps; documentation was adopted into the team's internal wiki.
• Resolved 12 Level 1 support tickets (IAM permission errors, S3 bucket access issues, EC2 connectivity troubleshooting) within agreed SLA windows under senior engineer supervision.

AWS, Docker, Terraform, Python

• Deployed a personal portfolio website on AWS: static files hosted in S3, CloudFront for global CDN delivery, Route 53 for custom domain, and ACM for HTTPS; site loads in under 1.5 seconds from India, Singapore, and the US.
• Built and containerised a Python Flask REST API using Docker; created a Docker Compose setup for local development pairing the app with a PostgreSQL container; pushed images to Docker Hub with versioned tags.
• Provisioned an EC2-based web server using Terraform (VPC, public subnet, security group, EC2 instance, Elastic IP) with an S3 backend for Terraform state; first hands-on experience applying infrastructure-as-code principles.
• Automated a weekly AWS cost report using Python and boto3: queries Cost Explorer, formats a summary, and sends it via SES; deployed as an AWS Lambda function with an EventBridge cron trigger, running reliably for 4 months.
