Status● Active

I build and automate cloud infrastructure on AWS. My focus is on designing highly available, scalable systems and engineering CI/CD pipelines that take code from commit to production with zero manual intervention.

Currently in my third year of Computer Engineering at the University of Ruhuna, I'm working toward a career in SRE and DevOps engineering. I completed a 6-month DevOps and Linux Administration training program with WSO2, and I'm actively pursuing multiple cloud certifications.

04Mission Log

Completed Missions

Deployed

VProfile Local Stack

Multi-Tier Web App on Local VMs

Manually deployed a multi-tier Java web application across five VMs using Vagrant and VirtualBox. Nginx reverse proxy, Tomcat, RabbitMQ, Memcached, and MySQL — all orchestrated locally to understand networking and service dependencies from the ground up.

Key Results

Orchestrated 5 VMs with automated DNS host mapping. Secured services with firewalld rules. End-to-end validated with backend data retrieval and active RabbitMQ connections.

AWS Lift & Shift

Multi-Tier Web Application Deployment

Migrated the same Java stack from local VMs to AWS EC2. Automated provisioning with Bash user data scripts, high availability with ALB across three AZs and private Route 53 DNS.

Cloud-Native Re-Architecting

Migration to AWS Managed Services

Re-architected by replacing self-managed EC2 with AWS Managed Services. Streamlined delivery with Elastic Beanstalk and enhanced global performance with CloudFront CDN and ACM for HTTPS.

Automated CI/CD Pipeline

VProfile Application — Continuous Delivery

The final phase of the VProfile evolution — a fully automated CI/CD pipeline that eliminates all manual intervention. AWS CodePipeline orchestrates the end-to-end workflow from Bitbucket commit to Elastic Beanstalk production deployment, with CodeBuild handling automated compilation, testing, and artifact creation via Maven.

Key Results

Reduced end-to-end deployment from 30-60 minutes to under 10 minutes. Zero-touch workflow with build-time validation — only tested code reaches production. Strict least-privilege IAM policies across all pipeline stages.
