During July 2025, contributed to thesysdev/crayon by enhancing header customization across the application. Developed and integrated a rightChildren prop for both Header and MobileHeader components, enabling injection of custom right-aligned content to support diverse page-specific actions. This work involved thoughtful React component API design, prop-driven architecture, and careful SCSS styling adjustments to maintain layout consistency. Additionally, removed an unused prop from MobileHeader, streamlining the codebase and reducing maintenance overhead. The update improved UI flexibility and accelerated feature iteration, leveraging TypeScript and frontend development best practices to deliver a more adaptable and maintainable user interface without introducing regressions.
