Saikat S.

I am an experienced AWS DevOps Engineer with deep expertise in automating the full software development lifecycle (SDLC) using CI/CD pipelines and Infrastructure as Code (IaC). I specialize in architecting, deploying, and operating highly scalable and resilient microservices on Amazon EKS. My experience includes designing and implementing active-active and active-passive multi-region architectures on AWS to achieve Disaster Recovery (DR), High Availability (HA), fault tolerance, and low-latency performance for mission-critical applications. I work extensively across the AWS ecosystem, including VPC design, ALB/NLB, Route 53, Amazon ECS/EKS, IAM, AWS WAF, RDS/Aurora Global Database, DynamoDB Global Tables, ElastiCache, and S3. I build production-grade CI/CD pipelines using AWS CodePipeline, GitHub Actions, and bitbucket, incorporating automated testing, security scanning, and zero-downtime deployments. I also leverage Terraform and CloudFormation for IaC, ensuring repeatable, secure, and scalable infrastructure provisioning. My skill set spans observability (CloudWatch, Prometheus/Grafana, OpenTelemetry), security hardening (IAM least privilege, KMS encryption, Secrets Manager, Parameter Store), and implementing best practices for network segmentation, container security, and Kubernetes governance. I’ve successfully handled large-scale migrations, cluster upgrades, cost optimization, and performance tuning across distributed systems in production environments.
