Vikas Vishwakarma enhanced the Lead Management module in the krayin/laravel-crm repository by implementing dynamic display and drag restrictions for 'won' and 'lost' stages. He refactored the stage handling logic using Blade, JavaScript, and PHP to remove redundant translations and improve UI consistency. His work ensured that only user-defined stages are draggable, while default 'won' and 'lost' states remain protected from modification. This update addressed issue #2378 and improved maintainability and clarity in the user interface. The depth of the changes reflects a strong grasp of frontend development, localization, and UI/UX principles within a Laravel-based CRM context.
