Worked on the wundergraph/cosmo and cosmo-docs repositories to deliver six core features focused on automation, reliability, and developer experience. Developed a persisted operations deletion API with updated protobuf schemas, and enhanced the CLI by adding robust JSON output and file redirection support for improved scripting. Overhauled CI/CD pipelines using GitHub Actions, introduced pre-commit formatting with ESLint and Prettier, and re-enabled linting to enforce code quality. Improved documentation structure and updated READMEs for clarity and usability. Utilized TypeScript, JavaScript, and Shell scripting throughout, emphasizing backend development, schema validation, and technical writing to streamline workflows and support safer releases.
