Worked on stabilizing template rendering in the LimeSurvey/LimeSurvey repository by addressing a bug related to unclosed Twig comments in the Vanilla and Fruity_Twentythree themes. Applied PHP and Twig skills to resolve UI display issues, ensuring theming consistency and reducing support requests tied to rendering glitches. Delivered a targeted, low-risk patch with a single-file change, maintaining clear commit traceability for future maintenance. The solution involved debugging template compatibility and performing end-to-end verification across affected themes. This work improved user experience and theme reliability, demonstrating proficiency in front end development and careful attention to maintainable, business-critical code quality.
