Jinhda Douang developed a new visual theme for the Neo product within the OPEN-ENT-NG/magneto repository, focusing on UI theming improvements over a one-month period. The work centered on SCSS, leveraging CSS and frontend development skills to define primary and secondary color variables and customize the header navbar background, ensuring consistent branding. All changes were scoped exclusively to the SCSS file, which allowed for safer iterations and minimized risk to the existing codebase. No major bugs were addressed during this period, reflecting a targeted approach that prioritized UI enhancements while maintaining release velocity and stability for ongoing product development.
