Avinash Dola focused on front-end development within the PolicyEngine/policyengine-app repository, addressing UI maintainability by refining the project’s color palette. He removed the deprecated 'green' color from the colors.js file, ensuring that only current design tokens remained in use. This JavaScript-based cleanup reduced visual drift and simplified theming, making future iterations more efficient and minimizing styling inconsistencies across components. Although the work centered on a single bug fix rather than new feature development, it demonstrated attention to codebase hygiene and design system clarity. Avinash’s contribution improved the overall maintainability and consistency of the application’s user interface.
