Managed and optimized AWS infrastructure across EC2, ECS, EKS, VPC, IAM, Route 53, S3, and CloudWatch, maintaining 99.9% uptime for enterprise-scale healthcare data workloads. • Reduced MTTR by 30% by engineering CloudWatch alarms + SNS notification routing for ECS/EKS workloads, enabling real-time incident detection and automated alerting in 24/7 production environment. • Decreased deployment time by 25% by provisioning standardized multi-environment infrastructure using Terraform modules and Ansible configuration management across dev, staging, and production. • Achieved 40% reduction in build times by implementing parallel processing in GitLab CI/CD pipelines and migrating legacy Jenkins pipelines to GitLab, simplifying deployment workflows. • Built end-to-end observability stack using Prometheus, Grafana, Datadog, and CloudWatch, enabling early detection of performance degradation and proactive incident prevention. • Implemented ArgoCD GitOps workflows for automated Kubernetes deployments, ensuring Git as the single source of truth across multiple EKS clusters and environments. • Maintained HIPAA compliance across all infrastructure, enforcing IAM least-privilege, secrets management, vulnerability monitoring, and secure configuration practices aligned with NIST 800-53. • Engineered CI/CD quality gates using SonarQube (85-90% coverage threshold) and Trivy security scanning, blocking non compliant code from reaching production. • Upgraded RabbitMQ and migrated messaging infrastructure to AWS MQ, improving system reliability, version compatibility, and message delivery guarantees across distributed services. • Supported Kafka-based event streaming pipelines in AWS, ensuring high availability and data integrity for real-time healthcare data processing. • Coordinated cross-team release planning and incident response across Dev, QA, Infrastructure, and Security teams, applying Agile/Scrum methodology to ensure on-time delivery.
