Worked on the formbricks/formbricks repository to enhance API reliability by addressing error handling in the User Creation API. Focused on improving client feedback, the developer implemented a fix that returns a 409 Conflict response when a duplicate email is detected during user creation, replacing the previous 500 Internal Server Error. This adjustment aligns the API with HTTP standards and reduces confusion for clients integrating with the service. The work involved TypeScript and emphasized skills in API development, error handling, and testing. By standardizing error responses, the update helps prevent downstream issues and supports a smoother developer experience for API consumers.
