Worked on the cloudposse/atmos repository to enhance the integrity and compatibility of JSON file handling. Addressed a bug by implementing a solution in Go that ensures all JSON files written to disk end with a newline character. This approach standardized file endings, improving readability and aligning with project conventions while reducing unnecessary diffs in version control. The update also minimized potential parsing issues in automated workflows and downstream integrations that rely on consistent file formatting. Leveraged skills in Go development, file handling, and JSON processing to deliver a targeted fix that supports smoother CI processes and better interoperability with external tooling.
