During February 2026, contributed to the n8n-io/n8n repository by developing a Sticky Notes Color Customization feature for the editor UI. This work introduced a custom color picker with both preset options and hex input, enabling users to dynamically change sticky note colors. The implementation involved updating Vue components and related utilities to support consistent color rendering and behavior throughout the interface. Comprehensive tests were added to verify color changes and user interactions, enhancing both user experience and maintainability. The project leveraged JavaScript, TypeScript, and front end development skills, focusing on UI design and robust testing practices to ensure reliability.
