Systems Architect Developer in Kalutara, Western Province, Sri Lanka

Migrated an EC2 deployed clinic management system of a Singapore client to AWS Fargate. I used Terraform to create the ELB, target groups, ECS task definitions, and ECS Fargate service creation. For the CI/CD pipeline, I used GitHub actions to deploy the applications to staging and production environments.
