Configured Cluster Autoscaler and Karpenter for automatic node group scaling, reducing
downtime under load and optimizing compute costs (~20% savings).

DocumentDB, MQ) with remote state in S3 + DynamoDB. Implemented reusable modules for
dev/stage/prod environments.
- Built CI/CD pipelines in GitLab CI with dynamic environments (review apps), Helm-based
deployments to EKS, and automatic rollback on health check failures. Deployment time reduced
from 15 to 5 minutes.
- Implemented centralized logging and monitoring: Loki + Grafana for logs, Prometheus +
NewRelic + CloudWatch for metrics, configured Slack alerts. Enabled observability for 8+
services.
- Migrated services from DigitalOcean to AWS ECS/Fargate and EKS using AWS CDK for
infrastructure as code. Improved availability from 99.5% to 99.9%.
- Configured asynchronous service communication via SQS (with DLQ and exponential retries)
and SNS, plus RabbitMQ for guaranteed message delivery.
- Integrated AWS DocumentDB (MongoDB-compatible) with K8s applications, configured
