Over a two-month period, contributed to both the slackapi/bolt-js and sanity-io/sanity repositories by delivering targeted feature enhancements and maintaining codebase stability. In slackapi/bolt-js, focused on release management by publishing two version updates, reverting an experimental auto-acknowledgement flag, and refining middleware and type definitions to ensure backward compatibility. For sanity-io/sanity, expanded the CLI’s capabilities by introducing support for blueprint function types that handle document changes, along with new filters for drafts and all versions, and updated the CLI help text accordingly. Work emphasized API and CLI development, leveraging JavaScript, TypeScript, and Node.js for robust, maintainable solutions.
