Rajesh D.

Hi, I’m Rajesh Kumar Das, a hands-on DevOps engineer passionate about building reproducible, automated, and developer-friendly infrastructure that accelerates software delivery with stability and transparency. I’ve accomplished scalable infrastructure automation by designing modular, declarative systems leveraging Kubernetes (k3s), GitOps (FluxCD), and HashiCorp Vault, improving deployment reliability and security. At Wipro (serving Cigna Healthcare), I built AWS test automation frameworks that cut regression times by 87%, and at Kubecraft, I architected GitOps-managed homelab clusters that reduced setup time by over 95%. My expertise spans infrastructure-as-code (Terraform, Ansible, Helm), container orchestration (Docker, Kubernetes), CI/CD pipelines (GitHub Actions, Jenkins), and robust testing and validation frameworks. I thrive on automating complex workflows, from environment bootstrapping and configuration management to shift-left testing, to deliver consistent developer experiences and faster feedback cycles.
