Worked on the source-academy/frontend repository to enhance the CSE Machine’s user interface and performance, focusing on interactive arrow highlighting, improved selection logic, and persistent visual states. Leveraged React, Konva, and TypeScript to refactor arrow state management, introduce color-coding for better visibility, and implement origin-based arrow filtering with dedicated UI controls. Addressed performance by removing redundant draw calls, reducing render cycles, and updating test automation and linting for code quality. Enhanced function value tooltips and layout for clearer presentation, while collaborating on co-authored commits. The work resulted in a faster, more maintainable, and accessible front end for algorithm visualization.
