Kullas focused on enhancing cloud infrastructure for the companieshouse/acsp-api, acsp-web, acsp-confirm-client-id-verification-web, and file-validation-api repositories by standardizing ECS autoscaling and improving resilience across staging environments. Using Terraform and AWS ECS, Kullas unified autoscaling parameters, optimized resource allocation, and prepared services for performance testing, which streamlined deployments and improved resource utilization. The work included cleaning up Terraform variable formatting for maintainability and removing deprecated components to simplify deployment topologies. By aligning CPU, memory, and autoscaling configurations, Kullas enabled more predictable scaling behavior and smoother release cycles, demonstrating a strong grasp of infrastructure as code and DevOps best practices.
