I'm a DevOps (Platform) Engineer Intern at Sysco LABS Sri Lanka and a Computer Engineering undergraduate at the University of Ruhuna. I care about the boring things that make software reliable: infrastructure as code, CI/CD, observability, and platforms that let developers ship without thinking about the plumbing.
Before Sysco LABS, I was selected from 7,000+ applicants for the WSO2 Linux Systems Administration & DevOps Engineering Training Program — a 6-month intensive where I served as group leader for the capstone project, a cloud-native reservation system on a self-hosted Kubernetes cluster.
I'm an AWS Certified Solutions Architect – Associate, currently studying for the CKA and the HashiCorp Terraform Associate, and a FIDE-rated chess player (1641 classical).
Working on platform engineering for one of the world's largest foodservice companies: Kubernetes on EKS, GitOps with ArgoCD, pipelines on Concourse CI, observability with Datadog, and infrastructure as code across AWS.
Selected from 7,000+ applicants for a 6-month intensive covering Linux administration, networking, containers, and cloud. Served as group leader for the capstone — Phoenix Booking, a group of 10 building on a self-hosted 5-node Kubernetes cluster.
Undergraduate specializing in computer engineering — systems programming, networking, and cloud computing. Entered via A/L Physical Science stream with AAB (Z-score 1.8440).
Currently preparing for the Certified Kubernetes Administrator exam — running self-hosted clusters with kubeadm, EKS and GKE — on the road to the full Kubestronaut title. Also studying for the HashiCorp Terraform Associate certification.
WSO2 capstone — led a group of 10 building a cloud-native hotel reservation system on a self-hosted 5-node Kubernetes cluster (kubeadm via Ansible, Terraform-provisioned AWS across 3 AZs) — running $73/month cheaper than managed EKS.
A 7-stage Jenkins declarative pipeline for a 5-service containerized freights app — Terraform provisioning, Ansible Vault secrets, Trivy scanning, ALB path routing with TLS, CloudWatch + SNS alerting.
Fully automated delivery with CodePipeline + CodeBuild, deploying a Java app to Elastic Beanstalk with an RDS backend. Cut deployment time from 60 minutes to 10 with zero-touch, build-validated releases.
Replaced self-managed EC2 services with AWS managed equivalents — RDS, ElastiCache, Amazon MQ, Elastic Beanstalk — fronted by CloudFront with ACM edge HTTPS. Zero self-managed servers.
Migrated a multi-tier Java stack to EC2 with an ALB across 3 availability zones, Auto Scaling (1–4 instances), custom AMIs, private Route 53 DNS, and a fully isolated data tier.
Where it all started — a 5-VM distributed system orchestrated with Vagrant + VirtualBox: Nginx, Tomcat, RabbitMQ, Memcached, MySQL, hardened with firewalld and automated DNS host mapping.
Earned admission to Thurstan College, Colombo 07 — one of Sri Lanka's most prestigious national schools, in the heart of the educational triangle.
Nine A passes at the Ordinary Level Examinations. Five years of discipline and competition at one of Colombo's finest schools.
Physical Science stream — securing admission to the Faculty of Engineering, University of Ruhuna.
Chose Computer Engineering and discovered a passion for infrastructure — systems, networking, and automation.
Selected for the 6-month Linux SysAdmin & DevOps intensive. Served as group leader for the Phoenix Booking capstone project.
Passed the AWS Solutions Architect – Associate (SAA-C03) and joined Sysco LABS Sri Lanka as a DevOps (Platform) Engineer Intern. The mission continues.
Volunteered as a Mathematics instructor for the Mehewara programme by the Faculty of Engineering, University of Ruhuna — hands-on maths workshops for O/L students across the Colombo district.
Member of the Delegates Team for CareerXpo 1.0, the career fair by the IEEE Student Branch and ICES Society, University of Ruhuna — coordinating industry delegates and event logistics.
