Worked on the Significant-Gravitas/AutoGPT repository to enhance reliability and correctness in API interactions, focusing on frontend and authentication edge cases. Addressed a bug in URL construction by filtering out null values from query parameters using TypeScript, preventing malformed URLs and issues with downstream integrations. Implemented a canonical host redirect from www to non-www with a 308 status code, ensuring OAuth callbacks preserved HTTP methods and bodies, which reduced authentication flow errors and cookie domain mismatches. Demonstrated strong collaboration across frontend and backend boundaries, applying Next.js and TypeScript skills to improve API reliability and maintain consistent authentication experiences for users.
