Worked on the aws-games/cloud-game-development-toolkit repository to deliver comprehensive documentation and deployment guidance for a new TeamCity module, supporting AWS ECS with EFS and Aurora Serverless integration. Used Markdown and HCL to create architecture diagrams, usage examples, and updated MkDocs navigation for clearer onboarding. Enhanced CI/CD infrastructure by improving Packer configurations for Windows build agents, enabling runtime AWS region selection and increasing the default instance size from t3.small to m5.large for better build performance. Focused on aligning infrastructure and documentation to support scalable, reliable TeamCity deployments on AWS, streamlining both developer onboarding and ongoing CI/CD operations without introducing bugs.
