Worked on the sublime-security/sublime-rules repository to standardize the HTML XPath API across detection rules by renaming the beta.html_xpath field to html.xpath, ensuring consistent naming conventions without altering existing functionality. This refactor improved the stability and usability of the XPath API, making it easier for developers to onboard and reducing future maintenance risks. The work demonstrated skills in detection rule development, API design, and change management, with all modifications tracked to a specific issue for traceability. Technologies used included YAML for rule definitions and XPath for query logic, focusing on maintainable, developer-friendly detection rule infrastructure within the project.
