About
About Me
Hi, I'm Warusha Yohan
I am a passionate DevOps Engineer with a strong foundation in full-stack development. I specialize in transforming complex manual processes into automated, scalable, and secure cloud environments. My goal is to empower development teams to ship code faster and more reliably.
Cloud Architecture
Designing resilient, highly available, and cost-optimized infrastructure on AWS, Azure, and GCP.
CI/CD Automation
Building seamless deployment pipelines using GitHub Actions, Argo CD, and Jenkins to accelerate delivery.
Infrastructure as Code
Provisioning and managing environments predictably using Terraform, Docker, and Kubernetes.
Full-Stack Integration
Bridging the gap between Dev and Ops with hands-on experience in React, Node.js, and Python.
From first conversation to a system your team owns.
Discovery
A focused look at your current infrastructure, deployment bottlenecks, and security constraints. We end with a clear roadmap for modernization.
Architecture
System design before implementation: Hub-and-Spoke topologies, modular Terraform structures, and defining zero-trust secrets pipelines.
Provisioning
Building the foundation using Infrastructure as Code. Setting up scalable Kubernetes clusters, container registries, and GitOps workflows.
Production
Hardening the environments: configuring auto-scaling, Prometheus/Grafana observability, and enforcing network policies at real volume.
Enablement
Your team takes it from here. Full handoff with documentation, CI/CD walkthroughs, and best practices to keep infrastructure drift-free.
Expertise
Technical Arsenal
Tools and technologies I use to build, deploy, and maintain robust infrastructure.
