• Found areas of optimization in AWS expenditure, reduced costs by around $4000/month through effective resource allocation in areas such as underutilized EC2 instances, optimized S3 storage classes, EBS Volumes, etc • Worked on migrating apps in the dev environment from docker-compose to Kubernetes ( EKS). Managed DNS configuration, load balancing, and proxying via Nginx, and instance provisioning for existing microservices.• Created scripts for automating key tasks on Windows and Linux servers, including GUI tools for 3rd party applications, and data backups to S3. Set up multiple groovy pipelines in Jenkins for Production and Dev Environments as well as crons for ad-hoc tasks.• Transitioned logging from AWS CloudWatch to the ELK Stack, enhancing log analysis capabilities; integrated Grafana and Prometheus for improved alerting and monitoring. Set up notifications via Slack and Opsgenie for the same.• Reduced Build Time of Dev Environments by optimizations in the docker images that cut build times by 70%, accelerating development and deployment cycles.

• Migrated some of the existing AWS Infrastructure into IaC using Terraform and Ansible. This improved management and version control, making it easier to replicate and modify environments.• Collaborated with the team to ensure the organization's cloud data practices met SOC 2 compliance requirements. Setup Audits for different cloud services and controlled IAM Permissions across the team.• Configured application firewalls using WAF to block specific IPs based on set rules, including alert systems for threshold breaches and DDoS attacks.• Addressed Vulnerabilities detected on EC2 Instances, Lambdas and Java Applications thus reducing potential risks and improving overall system stability.
