Worked on the unity-sds/unity-monorepo, delivering two features focused on infrastructure security and automated quality assurance. Developed a CloudFormation update that removed outdated IAM policies, reducing the IAM surface area and simplifying configuration management. Built an automated landing page verification framework using Python, Selenium, and AWS SSM, enabling nightly end-to-end tests with robust timeout and error handling. Leveraged Docker for isolated test execution and ensured reliable cleanup of test environments. Emphasized stability by making tests unconditional and improving retry logic, resulting in more predictable deployments and faster detection of regressions. No bugs were reported or fixed during this period.
