New QuantaMinds System
A full-stack web application that combines a public-facing marketing website with a comprehensive admin panel featuring AI-powered proposal generation, CRM pipeline management, invoicing, and a fully integrated CMS — all built from scratch with no external CMS dependencies.
QuantaMinds is a custom-built business management platform designed to streamline every stage of the client lifecycle — from first contact to final invoice. The public website features 10 fully editable CMS sections, a multi-layered secure contact form, and a dynamic project portfolio. Behind the scenes, a powerful admin panel gives business owners complete control over their operations.
The admin dashboard includes a full CRM with lead tracking and timeline history, a Kanban-style proposal pipeline, and project management boards with drag-and-drop state transitions. One of its standout features is AI-powered proposal generation: using Anthropic's Claude API, the system analyzes lead data — industry, budget, project scope — and produces polished, professionally structured HTML proposals in seconds. These proposals can be refined with a rich text editor, exported as PDF, and emailed directly to clients.
The platform also includes a complete invoicing system with sequential numbering, dynamic line items, configurable tax rates, flexible payment terms, PDF generation, and automated email delivery with retry logic.
Every piece of content on the public website — headlines, stats, service descriptions, testimonials — is managed through the admin panel's built-in CMS, with intelligent fallbacks to default values if the database is unreachable.
