CRM

Build a modern, intuitive Sales CRM web application centered around a dynamic drag-and-drop Kanban deal pipeline board. The pipeline board should allow sales reps to move deals seamlessly across customizable sales stages such as Lead In, Qualification, Proposal Sent, Negotiation, and Closed Won. Include a comprehensive Contact and Company directory table with global search, sorting, and multi-tag filtering. Create detailed record side-drawers for deals and contacts where team members can log call notes, upload document attachments, assign task reminders with due dates, and view a complete chronological activity feed. Implement customizable deal tags and lead priority flags. Include dynamic revenue calculation summaries displaying total pipeline value and win probability weighted forecasts across each stage column. Construct a dedicated tasks manager view for sales reps to track daily follow-ups. Finally, build an executive Sales Analytics dashboard featuring bar charts for revenue velocity, conversion rate analytics, overdue task summaries, and individual team member performance leaderboards.
