• Orchestrated the multi-region deployment of a VPC, EC2 auto-scaling groups, and RDS instances using Terraform, reducing provisioning time from 3 days to 15 minutes and ensuring environment consistency.
• Managed Terraform state files remotely using S3 and DynamoDB for state locking, enabling secure collaboration across a team of 3 engineers and eliminating state conflicts.
• Authored Python scripts to automate the cleanup of unused EBS snapshots and old AMIs, reducing monthly storage costs by 15%
• Developed a Bash monitoring script that parsed system logs and automatically restarted failed services, decreasing manual intervention tickets by 90%
• Led a cost-optimization initiative by implementing AWS Budgets, identifying and rightsizing underutilized EC2 and RDS instances, resulting in a 25% reduction in monthly cloud spend $30,000 annual savings.
• Leveraged AWS Savings Plans for committed compute usage, reducing on-demand spending by %15 without impacting application performance or availability.
• Modernized a legacy application by re-architecting it into Docker containers deployed on AWS ECS Fargate, eliminating server management and improving scalability during traffic spikes
• Engineered the lift-and-shift migration of 50 on-premise physical servers to AWS EC2, completing the project 2 weeks ahead of schedule and improving system uptime to [99.9%]
• Hardened 100 RHEL 8 servers per CIS benchmarks using Ansible, successfully passing security audits and eliminating critical vulnerabilities.
• "Built and maintained custom RPM packages for internal software, standardizing deployments across multiple production servers and ensuring version consistency.
• Designed and implemented a highly available architecture across three Availability Zones using Application Load Balancers, Auto Scaling Groups, and Multi-AZ RDS, achieving [99.99%] uptime
• Enhanced security posture by implementing VPC Flow Logs, security groups, and NACLs to enforce a zero-trust network model, preventing 0 attempted unauthorized access attempts.
• Implemented a centralized monitoring solution using Cloud Watch, Grafana, and Prometheus, decreasing mean time to resolution (MTTR) for incidents by 20%
• Consolidated application and system logs from 10 EC2 instances into AWS Cloud Watch Logs, enabling faster debugging and creating actionable dashboards for the operations team.
• Diagnosed and resolved a chronic disk I/O bottleneck on a database server by analyzing iostat metrics and migrating to provisioned IOPS EBS volumes, improving query performance by 25%
