Jinhda Douang developed a new visual theme for the Neo product within the OPEN-ENT-NG/magneto repository, focusing on UI theming improvements using SCSS and CSS. The work involved defining primary and secondary color variables and customizing the header navbar background to ensure consistent branding. By confining all changes to the SCSS styling file, Jinhda enabled safer iterations and streamlined future branding updates without impacting application logic. No major bugs were addressed during this period, which helped maintain release velocity while delivering targeted UI enhancements. The project demonstrated depth in frontend development and a methodical approach to maintainable, style-focused engineering.
