Cross-Platform Home Services & Technician App

Home Services App (Flutter + Modern Backend)

We built an on-demand home services platform with Flutter for iOS and Android, backed by a modern microservices backend (NestJS/Node.js). Customers can book plumbers, electricians, cleaners, and more; pick time slots; chat with providers; and track technicians in real time — while service partners, franchises, and dispatch teams manage jobs, pricing, and zones from a powerful web console.

The mobile client uses an advanced Flutter architecture with feature modules, deep-link routing, and smooth micro-interactions. On the backend, independently deployable services handle scheduling, pricing, routing, and notifications. Event-driven updates (WebSockets/messages) keep job status and technician locations synced across customer, provider, and dispatcher views.

Single Flutter codebase

The brand moved from messy phone/WhatsApp bookings to a structured on-demand experience, with higher technician utilization, clearer SLAs, and better customer satisfaction.

Problem

Before the app, the home services network struggled with:

  • Phone- and chat-based bookings with no centralized tracking or audit trail.
  • Technicians overbooked in some areas and idle in others due to poor routing.
  • No real-time view of job progress or ETA for customers or support teams.
  • Manual price negotiation, discounts, and upsells handled case-by-case.
Solution

We delivered a Flutter-powered booking & dispatch stack:

  • Flutter app with flows for service selection, slot booking, add-ons, and live tracking.
  • Provider & supervisor views for accepting jobs, route navigation, and closing work orders.
  • Microservices backend (NestJS/Node.js) for bookings, pricing, payouts, and notifications.
  • Admin & dispatcher web console for zoning, capacity planning, and SLA monitoring.
Outcome

The home services app now:

  • Owns the entire booking lifecycle, from request to rating, in one platform.
  • Improves utilization with smarter assignment based on skills, distance, and availability.
  • Reduces cancellations via clear ETAs, reminders, and technician communication.
  • Lets operations run targeted promos and dynamic pricing by zone, time, or category.

Architecture overview

The platform combines a modern Flutter client with a service-oriented backend, designed for high availability, observability, and fast feature delivery across multiple cities and partners.

  • Flutter client – Feature-based modules (Onboarding, Services, Booking, Jobs, Wallet, Profile) with advanced state management (e.g., Riverpod/GetX/BLoC) and guarded flows for customers vs technicians.
  • API gateway & services – NestJS/Node.js gateway routing to microservices: bookings, catalog, pricing, notifications, locations, and payouts.
  • Data & storage – PostgreSQL for relational data (jobs, users, payouts), Redis for caching slots/quotes, and object storage (S3-compatible) for images and documents.
  • Messaging & events – Message broker (RabbitMQ/Kafka) powering background jobs (notifications, reconciliation, reports) and event-driven workflows (job status, SLA breaches).
  • Maps, routing & zoning – Integration with mapping APIs to calculate travel time, zone coverage, and dynamic availability windows for each technician.
Advanced Flutter & backend features
Real-time job tracking

Live updates for “requested → accepted → en route → in progress → completed” with a technician map view and ETA recalculation based on traffic conditions.

Dynamic pricing & fees

Rule engine for base charges, visit fees, add-ons, and surge pricing by time, zone, or service category, all manageable from the admin console.

Technician app & route helper

Provider view in Flutter with job queues, navigation shortcuts, in-app chat, and photo-based proof of work after completion.

CI/CD & observability

Containerized services, environment-based configs, automated tests, metrics dashboards, and alerting across API, workers, and mobile builds.

The platform is ready for future expansions like subscription plans (maintenance packs), lead distribution to partners, and ML-powered dispatch & demand forecasting.

Home services capabilities
  • Category-based services (plumbing, electrical, AC, cleaning, appliances, more).
  • Instant and scheduled bookings with reschedule/cancellation rules.
  • In-app chat, notes, and photo attachments for problem description.
  • Ratings, reviews, and issue escalation flows post-service.
Tech stack & tooling
  • Flutter (Dart) for iOS and Android with modular, testable architecture.
  • NestJS/Node.js microservices backend with API gateway pattern.
  • PostgreSQL, Redis, message broker (RabbitMQ/Kafka), and object storage.
  • JWT/OAuth security, WebSockets, push notifications, deep links, analytics, and crash reporting.
Typical use cases
  • Home services brands launching a full on-demand booking app.
  • Franchise networks standardizing technician assignment and payouts.
  • Real-estate/property managers offering value-added maintenance services.
  • Any business that needs a scalable home services platform on Flutter + a modern backend stack.
