1. Project Vision & Business Value

1.1 What is KROW?

KROW is a workforce management platform that connects businesses (clients) with temporary/gig workers (staff) for event-based staffing needs. The platform handles the complete lifecycle from job posting to payment processing.

1.2 The Problem We Solve

Stakeholder Pain Point KROW Solution
Businesses Finding qualified temp workers is time-consuming and unreliable Instant access to pre-verified workers with ratings and certifications
Workers Inconsistent gig opportunities, delayed payments, opaque earnings Centralized shift discovery, real-time earnings tracking, transparent payment
Administrators Manual coordination between clients and workers, paper-based time tracking Automated assignment, QR/NFC clock-in, digital invoicing

1.3 Core Value Proposition

KROW = Uber for Event Staffing
  • For Clients: Post events, define shifts, get matched workers, track time, pay invoices
  • For Staff: Browse shifts, accept gigs, clock in/out, track earnings, get paid
  • For Admins: Manage workforce, verify profiles, resolve disputes, generate reports

1.4 Business Model

  1. Service Fees: Markup on worker hourly rates (configurable per business)
  2. Premium Add-ons: Optional services (uniforms, equipment, expedited matching)
  3. Enterprise Contracts: Long-term staffing agreements with volume discounts

1.5 Strategic Objective

Mission: Achieve complete technical independence by consolidating the KROW platform onto a single, robust, and maintainable ecosystem: Firebase & Google Cloud.

Guiding Principles:

  1. Velocity & Focus: Maximize productivity with Firebase Data Connect and generated SDKs
  2. Unified Backend: Single backend (Data Connect) powers all applications (Web, iOS, Android)
  3. Scalability & Low Overhead: Managed services minimize operational burden
  4. Data Ownership: Full control over PostgreSQL database for complex reporting
  5. Base44 as Design Accelerator: Treat Base44 as a prototyping tool, not a system to migrate
  6. Automation as Force Multiplier: Automate via Makefile and CI/CD pipelines

2. System Architecture (GCP Migration)

2.4 Key Architecture Decisions

  1. Firebase Data Connect as Primary API:

    • Auto-generates type-safe SDKs for all clients
    • Eliminates API versioning headaches
    • Direct PostgreSQL access with GraphQL abstraction

  2. Cloud Functions for Business Logic:

    • Email sending, AI invocations, file processing
    • Event-driven architecture for async operations
    • Clean separation from data layer

  3. Core API Services:

    • Document verification service
    • File upload service with signed URLs
    • LLM service for AI features (RAPID orders)
    • Integrated via ApiService (Dio-based)

  4. PostgreSQL Retention:

    • Full data ownership and portability
    • Complex queries and reporting capabilities
    • Industry-standard for enterprise requirements

3.3 Core Business Workflows

Workflow 1: Event Lifecycle

    participant API as Backend API
    participant Admin as Admin
    participant Staff as Staff App

    Note over Client,API: 1. Event Creation
    Client->>API: Create Event with Shifts & Positions
    API-->>Client: Event Created (Draft)
    Client->>API: Publish Event

    opt 2. Staff Assignment (Optional)
        Note over Admin,API: Optional Staff Assignment
        Admin->>API: Assign Staff to Shift

    Staff->>API: Clock Out

    Note over Client,API: 5. Post-Event
    Client->>API: Rate Staff
    API->>API: Generate Invoice
    Client->>API: Approve Invoice

Workflow 2: Staff Onboarding

1. Registration (Firebase Phone Auth)
   ├── Create Staff record (status: registered)
   └── Profile created with auth_provider_id

2. Profile Completion
   ├── Personal info (name, email, address)
   ├── Avatar upload
   ├── Emergency contacts
   └── Bank account details

3. Skills Declaration
   ├── Add skills with level/experience
   └── Status: pending → verified (admin)

4. Certification Upload
   ├── Upload certificates
   └── Status: pending → verified (admin)

5. Equipment Confirmation
   ├── Confirm uniforms per skill
   ├── Confirm equipment per skill
   └── Upload photos as proof

6. Profile Submission
   ├── Complete verification checklist
   └── Status: completed_profile → verified

But there is an ambiguity in the workflow. In the legacy application, worker verification happens at the beginning, and all workers are fully verified before they can access the application. In the new version, however, workers are allowed to access the application without being fully verified. This creates ambiguity in the following areas:

  • Definition of worker verification in the new system
    • Does verification mean the worker has fully completed their profile, or can a worker be considered verified with an incomplete profile?
  • Visibility of shifts for unverified workers
    • Should unverified workers be able to view the shifts page?

Workflow 3: Payroll Calculation

Work Hours = (clock_out - clock_in) - break_duration

Overtime Rules:
├── Regular Hours (1x):     hours <= 8
├── Overtime Hours (1.5x):  8 < hours <= 10
└── Doubletime Hours (2x):  hours > 10

Payment = (regular_hours × rate × 1.0)
        + (overtime_hours × rate × 1.5)
        + (doubletime_hours × rate × 2.0)
        + addons_amount

5. Data Connect & Development Strategy

5.1 Feature-Driven Schema Evolution

Principle: The Data Connect schema is not pre-designed. It evolves iteratively as features are implemented.

Feature Implementation Flow:
┌──────────────────┐     ┌──────────────────┐     ┌──────────────────┐
│   Pick Feature   │ ──► │  Define Schema   │ ──► │  Implement UI    │
│   from Sprint    │     │  Tables/Queries  │     │  with SDK        │
└──────────────────┘     └──────────────────┘     └──────────────────┘
         │                        │                        │
         │                        │                        │
         ▼                        ▼                        ▼
    No mocks!              Just enough               Generated SDK
    Real data              for feature               guarantees types
    from start

5.2 No Mock Data Policy

Why no mocks?

  1. Data Connect generates type-safe SDKs automatically
  2. Mocks create drift between expected and actual schemas
  3. Real data surfaces integration issues early
  4. Reduces "works on my machine" problems

Instead of mocks:

  • Use Firebase emulator suite for local development
  • Seed development database with realistic test data
  • Write schema migrations as features are added

5.3 Sprint 3 Schema Strategy

For each feature in Sprint 3:

  1. Identify Data Requirements

    • What entities does this feature need?
    • What fields are required vs optional?
    • What relationships exist?

  2. Write Schema Incrementally

    # legacy/dataconnect-v1/schema/event.gql
type Event @table {
  id: UUID! @default(expr: "uuidV4()")
  name: String!
  status: EventStatus!
  date: Date!
  business: Business! @relation
  hub: Hub @relation
  shifts: [EventShift!]! @relation
  createdAt: Timestamp! @default(expr: "request.time")
}

  3. Define Queries/Mutations

    # legacy/dataconnect-v1/queries/events.gql
query ListEvents($status: EventStatus) @auth(level: USER) {
  events(where: { status: { eq: $status } }) {
    id, name, status, date
    business { name }
  }
}

  4. Generate SDK & Implement UI

    firebase dataconnect:sdk:generate

5.4 Development Environment Setup

# Prerequisites
node -v    # >= 20.x
pnpm -v    # latest
fvm use    # Flutter version management
firebase --version  # >= 13.x

# Setup
git clone <repo>
cd krow-workforce-web
pnpm install
firebase login
firebase use development

# Start development
make dev              # Start all services
make dev-web          # Web only
make dev-mobile       # Mobile emulators
make sync-prototypes  # Sync visual references

5.5 Recommended Sprint 3 Feature Order

Based on minimal dependencies:

  1. Authentication Flow (depends: Firebase Auth only)
  2. Staff Profile Basics (depends: Auth)
  3. Event List View (depends: Auth, basic schema)
  4. Event Creation (depends: Auth, Events schema)
  5. Shift Assignment (depends: Events, Staff)
  6. Time Tracking (depends: Assignments)
  7. Invoice Generation (depends: Completed shifts)

6. Release Process & Automation

6.1 Versioning Strategy

Mobile Apps:

  • Format: v{major}.{minor}.{patch}-{milestone}
  • Example: v0.0.1-m4 (current release)
  • Milestones: m1, m2, m3, m4, etc.
  • Auto-extracted from apps/mobile/apps/{staff|client}/pubspec.yaml

Git Tags:

  • Format: {app-name}/{version}
  • Examples: staff/v0.0.1-m4, client/v0.0.1-m4

6.2 GitHub Actions Workflows

1. Product Release (.github/workflows/product-release.yml)

  • Trigger: Manual dispatch via GitHub UI
  • Purpose: Automated production releases with APK signing
  • Process:
    1. Extracts version from pubspec.yaml
    2. Builds signed APKs for both apps
    3. Creates GitHub release with changelog
    4. Tags release (e.g., staff/v0.0.1-m4)
    5. Uploads APKs as release assets
  • Secrets Required: 24 GitHub Secrets for APK signing (see docs/RELEASE/mobile-releases.md)

2. Hotfix Branch Creation (.github/workflows/hotfix-branch-creation.yml)

  • Trigger: Manual dispatch with version input
  • Purpose: Emergency fixes for production issues
  • Process:
    1. Creates hotfix/{version} branch from latest tag
    2. Opens PR back to dev branch
    3. Auto-updates PR description with hotfix checklist

3. Helper Scripts (.github/scripts/)

  • extract-version.sh - Extracts version from pubspec.yaml
  • generate-changelog.sh - Generates release notes from CHANGELOG
  • create-release.sh - Creates GitHub release
  • upload-assets.sh - Uploads APKs to release
  • build-apk.sh - Builds signed APK
  • tag-release.sh - Creates Git tags
  • hotfix-branch.sh - Creates hotfix branches
  • update-pr.sh - Updates PR descriptions

6.3 APK Signing Setup

Required GitHub Secrets (per app):

STAFF_UPLOAD_KEYSTORE_BASE64      # Base64-encoded keystore
STAFF_UPLOAD_STORE_PASSWORD       # Keystore password
STAFF_UPLOAD_KEY_ALIAS            # Key alias
STAFF_UPLOAD_KEY_PASSWORD         # Key password
STAFF_KEYSTORE_PROPERTIES_BASE64  # Base64-encoded key.properties

CLIENT_UPLOAD_KEYSTORE_BASE64
CLIENT_UPLOAD_STORE_PASSWORD
CLIENT_UPLOAD_KEY_ALIAS
CLIENT_UPLOAD_KEY_PASSWORD
CLIENT_KEYSTORE_PROPERTIES_BASE64

6.4 CHANGELOG Format

Each app maintains a separate CHANGELOG:

  • apps/mobile/apps/staff/CHANGELOG.md
  • apps/mobile/apps/client/CHANGELOG.md

Format:

## [Unreleased]

### Added
- New feature descriptions

### Changed
- Modified feature descriptions

### Fixed
- Bug fix descriptions

## [0.0.1-m4] - 2026-03-05

### Added
