01About

Cloud platforms that stay up, scale calmly, and cost less.

I'm an AWS-certified Senior DevOps Engineer from Sri Lanka with 5+ years of experience building, automating, securing, and optimizing cloud infrastructure across production AWS environments, Kubernetes migrations, CI/CD modernization, monitoring, incident response, and cost optimization.

I enjoy solving infrastructure problems, improving developer experience, reducing operational toil through automation, and building reliable cloud platforms that scale with the business.

04Selected work

Real systems, production-grade, shipped and supported.

Eight selected projects from the last few years — from EKS migrations to NFT-scale ticketing infrastructure and Terraform secure baselines.
Project 01cyan

Legacy Elastic Beanstalk → EKS Migration

Problem
Legacy Elastic Beanstalk apps were limiting scalability, deployment flexibility, and long-term maintainability.
Solution
Re-architected and migrated production workloads to a Kubernetes-based EKS platform with GitOps delivery and IaC-driven infrastructure.
Impact
Faster, safer rollouts with environment parity; improved scalability, observability, and platform consistency.

Major PHP Migration on AWS

Problem
Production PHP workloads needed to be upgraded across active Elastic Beanstalk environments without downtime.
Solution
Orchestrated a phased migration with automated rollbacks, environment validation, and end-to-end health checks.
Impact
Improved application compatibility, performance, and supportability across multiple production services.

Jenkins → EKS Cloud Nodes Migration

Problem
Existing Jenkins setup was slow, fragile, and bottlenecking developer productivity.
Solution
Re-platformed Jenkins onto EKS with elastic cloud-based agents provisioned on demand and managed via Terraform.
Impact
Significantly faster build times, improved reliability, and lower idle compute spend.
JenkinsAWS EKSKubernetesDockerTerraformEC2IAM
Project 04cyan

Dynamic EKS Environments for Automated Testing

Problem
QA cycles were slow because of shared, drift-prone test environments.
Solution
Built automation to spin up isolated EKS-based test environments per branch and tear them down after validation.
Impact
Faster QA turnaround, reliable test isolation, and improved developer confidence in releases.
AWS EKSKubernetesTerraformJenkinsGitHub ActionsDocker

AWS Cost Optimization Automation

Problem
Cloud spend was creeping up due to always-on non-production resources.
Solution
Designed scheduled start/stop and cleanup automations using Lambda, CloudWatch Events, and tagging policies.
Impact
Eliminated waste in non-production environments and trimmed monthly cloud spend with no developer friction.

Alerting & Monitoring Automation

Problem
Application issues were being detected too late, by users instead of operators.
Solution
Built unified alerting using Datadog, CloudWatch, and Lambda with intelligent Slack routing and noise reduction.
Impact
Faster MTTD/MTTR, fewer late-night pages, and clearer ownership of incidents.

NFT Live Ticketing Platform Infrastructure

Problem
Live NFT ticketing launch required highly available infrastructure to handle massive concurrent traffic.
Solution
Designed a resilient AWS architecture with autoscaling, WAF protection, and zero-downtime AB deployments.
Impact
Successfully supported ~15K concurrent users at launch with zero downtime.

Secure AWS Infrastructure with Terraform

Problem
Needed a repeatable, secure baseline for production AWS environments.
Solution
Authored Terraform modules with private networking, least-privilege IAM, KMS-backed secrets, and full logging.
Impact
Consistent secure-by-default infrastructure with auditable, version-controlled changes.
