Biswajit De developed the initial Vessel Management feature for the punchagency/YCC repository, focusing on enabling users to view and add vessels through a newly designed UI. He implemented React-based routing and state management to support seamless navigation and data handling within the module. The work included refactoring the user management page to integrate vessel-related functionality and updating SCSS styling to ensure visual consistency across the new and existing screens. By laying the foundational architecture for vessel tracking and management, Biswajit addressed core business requirements, though the scope was limited to feature delivery without documented bug fixes during this period.
