PROFILE
Tadashi-nakamura
Nakamura contributed to the mamezou-tech-site repository by authoring detailed infrastructure guides and automation scripts focused on Terraform and AWS. Over three months, Nakamura delivered a Terraform refactoring guide with a shell script template to enable non-disruptive resource renaming and module migration, reducing operational risk and streamlining Infrastructure as Code changes. He also documented the migration of a Sales Support System from EKS to ECS on Fargate, providing Terraform code for ECS, CloudMap, and API Gateway with JWT authentication. Additionally, Nakamura published a guide on using Terraform data sources to reference existing AWS resources, supporting incremental IaC adoption.

Dec 1, 2024During December 2024, delivered a new Infrastructure as Code (IaC) migration guide for the Sales Support System site, documenting migration from EKS to ECS on Fargate, evaluating service discovery options (CloudMap, ALB, NLB), and providing Terraform code to provision ECS, CloudMap, and API Gateway with JWT authentication. The work enhances deployment consistency, reduces manual toil, and accelerates onboarding for infra changes across teams. Key tech: AWS ECS/Fargate, EKS, Terraform, CloudMap, API Gateway, JWT; impact: faster provisioning, safer migrations, improved scalability.

Oct 1, 2024Delivered Terraform Refactoring Guide and Automation Script for mamezou-tech-site, enabling non-disruptive Terraform refactors (resource renaming within a module and moving resources between modules) and providing a shell script template to automate these tasks. This work reduces live-infrastructure risk, accelerates safe IaC changes, and establishes a reusable pattern for future refactors. No major bugs fixed in this period.
