Heather M. focused on backend development for the all-rit/ALL repository, addressing a critical issue in the account creation workflow. She identified and resolved a bug in UserService.js by reverting an earlier change that had incorrectly altered the email field from "email" to "email1." Using JavaScript, Heather restored the correct field usage, ensuring that new user accounts captured valid email addresses and maintained reliable onboarding communication. Her approach emphasized stability and traceability, implementing a low-risk, auditable fix with minimal code changes. This work improved the reliability of user sign-up processes and demonstrated careful attention to codebase integrity and maintainability.
