Chris Ryder engineered scalable and secure cloud infrastructure for the confirmation-statement-api and confirmation-statement-web repositories, focusing on ECS service autoscaling, environment-driven task counts, and enhanced logging. Using AWS, Terraform, and HCL, Chris upgraded Terraform modules, implemented root filesystem hardening, and streamlined configuration to reduce deployment complexity and improve operator control. In the file-validation-api repository, Chris delivered targeted Terraform module upgrades to ensure infrastructure stability and alignment with supported versions, minimizing drift and deployment risk. The work demonstrated depth in DevOps and Infrastructure as Code, emphasizing maintainability, security, and reliability across multiple environments without introducing new bugs during the period.
