Worked on the Unievent Planner frontend repository, focusing on a theme system migration to modernize the application's styling infrastructure. The project involved removing the legacy theme configuration file and all color definitions, laying the foundation for a potential transition to CSS-in-JS or an alternative theming solution. This migration aimed to improve maintainability and flexibility in the codebase, making future styling updates more manageable. The work was implemented using TypeScript and frontend development best practices, with an emphasis on clean code and traceable changes. No bugs were addressed during this period, as the primary focus remained on feature development and system migration.
