Developed secure FQDN normalization using Node.js and the URL API, implementing strict input validation and robust parsing to prevent malformed URLs and unauthorized path segments. Enhanced theme creation workflows by introducing user-friendly error handling through an admin wrapper, normalizing access requirement messages and ensuring clear feedback when theme write access is missing. Emphasized comprehensive unit testing and the use of Regex and TypeScript to validate edge cases, address malicious inputs, and maintain consistent, reliable behavior for both developers and end users.
