Worked on the runfinch/infrastructure and runfinch/finch repositories, focusing on cloud infrastructure, CI/CD automation, and Linux packaging over a three-month period. Delivered features such as CodeBuild security hardening, ARM-based build environment support, and improved project governance using AWS CDK, TypeScript, and CloudFormation. Enhanced CI reliability by tuning Ubuntu arm64 CodeBuild environments and implemented GitHub authentication for secure build processes. Automated Debian packaging and release workflows for the Finch project, leveraging GitHub Actions and shell scripting. Addressed CI/CD caching issues by updating IAM policies, enabling CloudFront invalidations, and ensuring faster, reproducible deployments across multiple environments and architectures.
