About Subrata Sikdar

Senior DevOps Engineer and CKA specializing in migrating monolithic applications to AWS EKS. I architect observable, self-healing infrastructure that serves millions of users with 99.95% uptime. With 4+ years of hands-on experience architecting production systems on AWS and Kubernetes, I specialize in transforming monolithic applications into resilient microservices architectures.My technical philosophy is simple: I don\'t just deploy infrastructure—I engineer solutions that scale reliably. Whether managing high-traffic EKS clusters or automating server configurations, I focus on stability, security, and observability.CORE COMPETENCIES: Kubernetes & Cloud Architecture: Leading zero-downtime migrations (15+ microservices) to AWS EKS, contributing to 99.95% production uptime. CI/CD Automation: Designing efficient pipelines using Jenkins, GitLab CI, and ArgoCD to reduce deployment times by ~35%. IaC & Configuration Management: Implementing reproducible infrastructure using Terraform and Helm, while leveraging Ansible for automated server provisioning and configuration management. Middleware & Application Runtime: Extensive experience managing and optimizing web servers (Tomcat, Nginx) for both legacy and cloud-native environments. Observability & Security: Building robust monitoring frameworks (Prometheus, Grafana, ELK) and implementing DevSecOps practices with Trivy and SonarQube.Currently, I am looking for Senior DevOps, SRE, or Platform Engineering opportunities where I can contribute to high-scale systems. I bring a blend of deep technical expertise—from Linux kernel tuning to complex AWS networking—and a business-first mindset.Certifications: Certified Kubernetes Administrator (CKA) AWS Solutions Architect - AssociateWhy Work With Me:I don\'t just deploy infrastructure—I architect solutions that scale. I\'m equally comfortable in Linux terminals optimizing performance, reviewing Terraform code, or designing observability strategies that give teams real-time visibility into production systems. My approach combines technical depth with business acumen, ensuring solutions align with organizational goals.Currently Exploring:I\'m actively open to Senior DevOps, SRE, and Platform Engineering opportunities where I can contribute to building and maintaining systems that serve millions of users reliably.Let\'s Connect If:Let\'s connect if you are looking for an engineer who can handle the full lifecycle of application delivery, from bare-metal configuration to container orchestration.
