# ProofPrep B2B Implementation Plan - Monorepo Architecture

This document outlines the strategic plan for extending ProofPrep with B2B functionality focused on enterprise HR departments and candidate screening, using a monorepo architecture for better separation of concerns.

## Executive Summary

ProofPrep will expand beyond its current B2C interview preparation model to offer B2B services enabling companies to:

* Screen candidates through AI-powered mock interviews
* Receive detailed feedback and ratings on candidate performance
* Focus recruiting efforts on the most qualified candidates
* Streamline the hiring process with data-driven insights

## B2C and B2B Integration Strategy

ProofPrep will maintain and enhance the existing B2C features while adding B2B functionality as parallel, integrated offerings using a monorepo architecture. This dual approach provides several advantages:

### Strategic Benefits

* **Dual Revenue Streams**: B2C subscriptions provide steady recurring revenue while B2B contracts offer higher-value engagements
* **Lead Generation**: Individual users can become advocates for B2B adoption at their companies
* **Market Coverage**: Serving both job seekers and employers creates a complete ecosystem around interview preparation
* **Shared Technology**: Core AI interview technology and feedback mechanisms serve both audiences

### Monorepo Architecture Approach

1. **Workspace Separation**
   * Dedicated applications for B2C (`/apps/web`) and B2B (`/apps/company`)
   * Shared component libraries in `/packages/ui`
   * Common utilities and services in `/packages/shared`
   * Domain-specific libraries (e.g., `/packages/interview`, `/packages/auth`)
2. **User Experience**
   * Independent but visually aligned experiences for personal and company users
   * Clear domain separation between the two applications
   * Consistent design language via shared UI component library
   * Common authentication for users across both applications
3. **Data Architecture**
   * Shared database with domain-specific collections
   * Cross-reference capabilities between B2C and B2B entities
   * Unified authentication system across applications
   * Shared API layer with application-specific endpoints
4. **User Journey Integration**
   * Seamless authentication across applications
   * Deep linking between B2C and B2B contexts
   * Shared notification system for cross-application events
   * User profiles accessible in both applications
