Here is the complete end-to-end architectural analysis of your marketplace ecosystem, showing how all pieces connect and how data flows through every step.
1. High-Level System Architecture
Your platform consists of 4 distinct subsystems operating around a single source of truth:
┌─────────────────────────────────┐
│ Next.js 16 Admin Panel │
│ (Operations & Control Plane) │
│ http://localhost:3000 │
└────────────────┬────────────────┘
│ Admin JWT (48 endpoints)
▼
┌──────────────────────┐ ┌─────────────────┐ ┌──────────────────────┐
│ kotlinFrontend │ │ Go Backend │ │ kotlinProvider │
│ (Customer App) ├─────►│ (Gin + GORM) │◄─────┤ (Provider App) │
│ Browse, Book, Pay │ Bearer│ Port 8080 │ Bearer│ Accept, Work, Earn │
└──────────────────────┘ JWT └────────┬────────┘ JWT └──────────────────────┘
│
▼
┌─────────────────┐
│ PostgreSQL │
│ 22 Core Tables │
└─────────────────┘
Subsystem Tech Stack Role in Marketplace
backend/ Go, Gin, GORM, PostgreSQL, JWT Central Engine: Houses all domain rules, state machines, financial transactions, and RBAC security.
admin-panel/ Next.js 16, TypeScript, Tailwind v4, TanStack Query Operations Center: Real-time marketplace monitoring, KYC approvals, dispatch management, payout release, disputes, and audit logs.
kotlinProvider/ Kotlin, Jetpack Compose, Hilt, Retrofit Field Partner App: Duty toggle (Online/Offline), incoming job alerts, GPS navigation, diagnosis, estimates, cash confirmation, and earnings.
kotlinFrontend/ Kotlin, Jetpack Compose, Retrofit Customer Consumer App: Registration, authentication, service discovery, booking creation, and tracking.
2. The Complete End-to-End Marketplace Flow (Step-by-Step)
Here is the exact lifecycle of how a service moves through the platform:
[ Phase 1: Onboarding ]
Provider registers on Android ──► Admin verifies KYC & Approves on Admin Panel ──► Provider goes Online
[ Phase 2: Booking & Dispatch ]
Customer creates Booking ──► System / Admin assigns Provider ──► Provider receives Dispatch Alert
[ Phase 3: Field Execution ]
Provider Accepts ──► Navigates ──► Arrives ──► Diagnoses ──► Customer Approves Estimate ──► Service Completed
[ Phase 4: Payment & Settlement ]
Customer pays (Cash or Online) ──► Invoice generated ──► Review submitted ──► Provider Payout queued
Step 1: Provider Onboarding & Verification
Registration: In
kotlinProvider
, a provider enters their phone number, receives an OTP via POST /api/v1/provider/otp/verify, and fills out their profile and documents via POST /api/v1/provider/register/step/:step.
Review State: Their account is set to status = "pending_approval".
Admin Verification: The operator opens the Admin Panel at /provider-applications, inspects the submitted documents, and clicks Approve (POST /api/v1/admin/providers/:id/approve).
Duty Toggle: Once approved, the provider opens their app and flips the Online switch (POST /api/v1/provider/availability/online). The pulsing radar dot turns emerald green.
Step 2: Customer Discovery & Booking Creation
Catalog Setup: Admin creates operating cities (e.g. Ghaziabad / Indirapuram) and service categories (e.g. AC Repair, Plumbing) via /services and /locations.
Customer Request: In
kotlinFrontend
(or via direct API), the customer selects a service, schedules a time, provides their address, and creates a booking (status = "booked").
Dispatch Matching:
Automatic/Manual Assignment: The backend or Admin Panel (/command-center or /bookings) assigns the booking to an online provider in that service zone (status = "assigned").
Step 3: Provider Job Lifecycle & Execution
The Go backend runs a strict, server-authoritative state machine in
provider_marketplace_service.go
:
ASSIGNED ──► ACCEPTED ──► ON_THE_WAY ──► ARRIVED ──► SERVICE_STARTED ──► COMPLETED
Accept / Decline: The booking appears in the provider's Active / Upcoming list. The provider taps Accept (POST /jobs/:id/accept).
Contact Release: Upon acceptance, customer details (name, address, entry instructions) are decrypted and released to the provider.
On The Way: The provider taps Navigate (POST /jobs/:id/navigate).
Arrival: The provider taps I've Arrived (POST /jobs/:id/arrive).
Diagnosis & Estimate:
Provider submits diagnostic notes & photos (POST /jobs/:id/diagnosis).
Provider creates an itemized estimate with labor and parts (POST /jobs/:id/estimates).
Once approved by the customer, work commences (status = "work_in_progress").
Completion: Provider marks checklist items done, uploads final service photos, and completes the job (POST /jobs/:id/complete).
Step 4: Payment, Invoice & Provider Payout
Payment Collection:
If Cash: Provider collects cash and confirms in app (POST /jobs/:id/payment/confirm-cash).
If Online: Payment gateway settles into platform escrow.
Invoice & Rating:
GORM automatically generates the GST/tax invoice record.
Customer submits a 1–5 star rating with feedback (POST /jobs/:id/rating).
Earnings & Settlement:
Provider's wallet balance increases: providerEarning = totalAmount - platformFee.
Admin monitors weekly payouts under /payouts and releases or holds disbursements.
3. Current State of Each Codebase
Component Status Recent Accomplishments
Go Backend (backend/) Complete & Running Auto-migrates 22 database tables, seeds default Super Admin (admin@services.com), 48 Admin API endpoints + 28 Provider Marketplace endpoints. Running on port 8080.
Admin Panel (admin-panel/) Complete & Running Next.js 16 dashboard with 22 authenticated routes (/command-center, /providers, /bookings, /payments, /payouts, /disputes, /audit-logs, etc.). 100% live database data. Running on port 3000.
Provider App (kotlinProvider/) Polished & Installed Built with Jetpack Compose. Redesigned with custom minimalist dock, animated radar availability switcher, earnings hero card, dispatches tab filter, and verified profile. Installed on your emulator.
Customer App (kotlinFrontend/) Initial Foundation Customer authentication (register, login, session tokens) is implemented. Service browsing and checkout screens are the next logical frontier.
4. Recommended Next Steps (How to Move Forward)
To take the platform from individual components into a cohesive, running product, follow this sequence:
Seed Live Test Data:
Create 1–2 test bookings in the database (or via the Admin Panel) assigned to your provider account phone (7906753589) to see the Active Hero Card and Upcoming Schedule populated with real data on the mobile emulator.
Customer App Expansion (kotlinFrontend):
Wire the customer app to browse the /categories and /services endpoints already exposed by the backend so customers can submit bookings from their phones.
Push Notifications / WebSocket Integration:
Hook up Firebase Cloud Messaging (FCM) or WebSocket events so when an Admin or Customer books a service, the Provider's phone rings instantly with a full-screen dispatch alert.
End-to-End Flow Test:
Perform a complete test run: Book in Customer App ➔ Dispatched in Admin Panel ➔ Executed in Provider App ➔ Invoiced & Settled in Admin Panel.file-2.js
