GuestAi acts as a virtual customer assistant, while Serene-AI is designed for spa and salon management. Ai-Artisan.v2 helps users build professional resumes. By bringing these together, we’re creating a comprehensive suite of AI-powered tools. Now, let's peek at the architecture that will make this unification possible.

Target Architecture: Building the Monorepo

The backbone of our unification is the target architecture, specifically the monorepo structure. Think of it as organizing all our apps and shared resources under one roof. Here’s how it’s structured:

W3JDev-AI-Ecosystem/
├── apps/
│   ├── punch-clock/          # HR & Attendance Management
│   ├── flair-ai/             # F&B Staff Training Platform
│   ├── waiter-ai/            # Restaurant Service Platform
│   ├── guest-ai/             # Virtual Customer Assistant
│   ├── serene-ai/            # Spa/Salon Management (NEW)
│   ├── ai-artisan/           # Resume Builder (REBUILD)
│   └── unified-dashboard/    # Central Control Hub (NEW)
│
├── packages/
│   ├── shared-ui/            # React component library
│   ├── ai-engine/            # Gemini + DeepSeek wrapper
│   ├── auth/                 # Multi-tenant SSO
│   ├── database/             # Unified Prisma schemas
│   ├── api-client/           # Type-safe tRPC SDK
│   ├── config/               # Shared configurations
│   └── utils/                # Common utilities
│
├── infrastructure/
│   ├── docker/               # Container configs
│   ├── github-actions/       # CI/CD pipelines
│   └── monitoring/           # Health checks & alerts
│
└── docs/
    ├── architecture/         # System blueprints
    ├── agent-personas/       # AI agent definitions
    └── api-reference/        # OpenAPI specs

Let's break this down:

• apps/: This directory houses each of our applications as separate entities within the monorepo. Each app, like punch-clock/ or flair-ai/, has its own codebase but can leverage shared resources.
• packages/: This is where the magic of code reuse happens. We have shared-ui/ for React components, ai-engine/ for our AI models, auth/ for authentication, database/ for unified database schemas, and more. By centralizing these, we avoid duplication and ensure consistency.
• infrastructure/: This handles the deployment and operational aspects. Docker configs, CI/CD pipelines, and monitoring tools live here, making sure our ecosystem runs smoothly.
• docs/: Documentation is key! Here, we’ll have everything from architecture blueprints to API references, ensuring everyone knows how the system works.

This structure allows us to share code, manage dependencies efficiently, and deploy consistently. Now, how are we going to build this? Let's move on to the implementation phases.

Implementation Phases: The Roadmap

We've broken down the unification into seven key phases, each with its own set of goals and deliverables. This structured approach helps us stay organized and track progress effectively. Let's walk through each phase:

Phase 1: Foundation (Weeks 1-2)

Lead Agent: @copilot (Architecture Agent)

This is where we lay the groundwork. The primary goal is to set up the monorepo structure and ensure everything builds correctly. Here’s what we're aiming for:

• [ ] Turborepo monorepo initialization
• [ ] Shared TypeScript/ESLint configs
• [ ] GitHub Actions CI/CD base
• [ ] Documentation structure
• [ ] Development environment setup

Success Criteria:

• ✅ All 6 apps build from the monorepo root
• ✅ Shared configs work across packages
• ✅ CI runs successfully on Pull Requests (PRs)
• ✅ Dev setup takes less than 5 minutes

We’re starting with the basics: setting up the monorepo, configuring shared settings, and ensuring our continuous integration (CI) pipeline is up and running. A smooth development environment setup is crucial for productivity.

Phase 2: Database Unification (Weeks 2-3)

Lead Agent: @copilot (Database Agent)

Next up, we tackle the database. The main objective is to create a unified database schema that works for all applications, with multi-tenancy and robust security measures. Here’s what’s on the agenda:

• [ ] Unified Prisma schema with multi-tenancy
• [ ] Row-Level Security (RLS) policies
• [ ] Migration scripts from existing databases
• [ ] Seed data for development
• [ ] Database performance optimization

Schema Preview:

model Organization {
  id              String   @id @default(cuid())
  name            String
  slug            String   @unique
  plan            Plan     @default(FREE)
  
  // Unified relations
  employees       Employee[]        // PUNCH-CLOCK
  restaurants     Restaurant[]      // WaiterAi/GuestAi
  trainingPrograms TrainingProgram[] // FlairAi
  resumes         Resume[]          // Ai-Artisan
  spaServices     SpaService[]      // Serene-AI
}

model User {
  id              String   @id @default(cuid())
  organizationId  String
  email           String   @unique
  role            UserRole
  
  organization    Organization @relation(fields: [organizationId], references: [id])
  
  // App-specific profiles
  employeeProfile Employee?
  staffProfile    StaffMember?
  resumeProfile   ResumeProfile?
}

Success Criteria:

• ✅ Single PostgreSQL instance for all apps
• ✅ Tenant isolation enforced at the database level
• ✅ Query performance less than 100ms average
• ✅ Zero data loss during migration

We’re aiming for a single, efficient database that serves all our applications while keeping data secure and isolated between tenants. This involves designing a unified schema, implementing security policies, and migrating existing data without loss.

Phase 3: Shared Packages (Weeks 3-5)

Lead Agent: @copilot (Package Developer Agent)

This is where we build the shared components that will power our ecosystem. The core idea is to create reusable packages for UI components, AI engine, authentication, and API clients. This phase is broken down into four sub-phases:

3A: UI Component Library (packages/shared-ui)

• [ ] Design system (Tailwind + Shadcn/ui)
• [ ] 50+ reusable React components
• [ ] Storybook documentation
• [ ] Dark/light themes
• [ ] Accessibility (WCAG 2.1 AA)

3B: AI Engine (packages/ai-engine)

// Unified AI service with auto-fallback
interface AIEngine {
  chat(prompt: string): Promise<string>
  voice(audioStream: Stream): Promise<Stream>
  analyze(data: any): Promise<Analysis>
  // Auto-switch: Gemini (primary) → DeepSeek (fallback)
}

3C: Auth Module (packages/auth)

• [ ] JWT + refresh tokens
• [ ] Multi-tenant middleware
• [ ] Role-based access control
• [ ] SSO integration

3D: API Client (packages/api-client)

• [ ] tRPC procedures for all apps
• [ ] Type-safe React hooks
• [ ] Optimistic updates
• [ ] React Query integration

Success Criteria:

• ✅ All packages published to private npm
• ✅ 90%+ test coverage
• ✅ Complete TypeScript definitions

We’re building a suite of reusable components and services that will streamline development across all applications. This includes a UI library, an AI engine with fallback capabilities, a robust authentication module, and a type-safe API client.

Phase 4: App Migration (Weeks 5-8)

Now, it’s time to move the individual applications into the monorepo and update them to use our shared packages. The goal here is to migrate each app with minimal disruption and ensure they work seamlessly within the unified ecosystem. The migration schedule is:

• Week 5: PUNCH-CLOCK
• Week 6: WaiterAi + GuestAi
• Week 7: FlairAi + Serene-AI
• Week 8: Ai-Artisan (complete rebuild)

Per-App Checklist:

• [ ] Migrate codebase to monorepo
• [ ] Update to shared packages
• [ ] Replace auth with unified module
• [ ] Migrate to Prisma database
• [ ] Update environment configs
• [ ] Verify feature parity
• [ ] All tests passing

Each app will undergo a series of updates to fit into the monorepo, including adopting shared packages, migrating to the unified database, and ensuring all features work as expected.

Phase 5: Unified Dashboard (Weeks 8-9)

Lead Agent: @copilot (Integration Agent)

With the apps migrated, we can now build a central dashboard. The main idea is to create a single control hub where users can access and manage all applications. Here’s what we envision:

// Central Hub Dashboard
interface DashboardWidgets {
  // Cross-app insights
  activeEmployees: number        // PUNCH-CLOCK
  attendanceRate: number         // PUNCH-CLOCK
  activeMenus: number            // WaiterAi
  trainingCompletion: number     // FlairAi
  recentApplications: number     // Ai-Artisan
  upcomingAppointments: number   // Serene-AI
  customerSatisfaction: number   // GuestAi
}

Deliverables:

• [ ] App switcher navigation
• [ ] Unified notification center
• [ ] Organization settings
• [ ] User management
• [ ] Analytics aggregation

This dashboard will provide cross-app insights and streamline user management, making it easier to navigate and use our ecosystem.

Phase 6: Deployment & Self-Healing (Weeks 9-10)

Lead Agent: @copilot (DevOps Agent)

Now, it’s time to deploy our unified ecosystem and ensure it runs smoothly. Our goal is to set up a robust deployment pipeline with self-healing capabilities. Here’s the infrastructure we’re planning:

Frontend: Vercel (all 7 apps) - $0 Hobby plan
Backend: Railway - $5/mo
Database: Supabase PostgreSQL - $0 Free tier
AI: Google Gemini + DeepSeek - $0 Free quotas
Storage: Cloudflare R2 - $0 (10GB free)
Monitoring: Better Stack - $0 Free tier

CI/CD Pipeline:

• [ ] Automated testing on PR
• [ ] Preview deployments
• [ ] Production deployment on merge
• [ ] Rollback on health check failure
• [ ] Automated dependency updates

Self-Healing:

• [ ] Health checks every 5 minutes
• [ ] Auto-restart on 3 failures
• [ ] Database connection auto-recovery
• [ ] AI provider auto-fallback
• [ ] Slack/Discord incident alerts

We’re setting up a CI/CD pipeline that automates testing, deployment, and rollback, along with self-healing mechanisms to ensure high availability and reliability.

Phase 7: Documentation (Weeks 10-11)

Lead Agent: @copilot (Documentation Agent)

Last but not least, we need to document everything! The aim is to create comprehensive documentation for the architecture, APIs, user guides, and more. Here’s what we’ll deliver:

• [ ] Architecture blueprint
• [ ] API reference (OpenAPI)
• [ ] User guides (all 6 apps)
• [ ] Developer onboarding
