Overview

On the customer side there is business discovery, a map, business details, booking, my appointments and live chat with the business. On the business side there is a calendar, day details, appointment confirmation and rescheduling, slot packages, the business profile and conversations.

Chat is real-time over SignalR, and notifications arrive through Firebase Cloud Messaging. A separate ASP.NET Core MVC panel lets businesses manage appointments, the calendar and messages from the web.

I also built the ASP.NET Core API behind the app: Clean Architecture, CQRS/MediatR, FluentValidation, EF Core, Repository/Unit of Work, JWT, rate limiting, Swagger, health checks, background services and Docker.

Highlights

Two-role app with separate customer and business shells (GoRouter StatefulShellRoute)
Live chat over SignalR and push notifications through FCM
Business discovery on a map (Google Maps, Geolocator)
A Dio interceptor that refreshes tokens automatically
Either<Failure, T> error handling with localized backend error codes
Premium membership groundwork (RevenueCat)

Architecture

Three-layer Clean Architecture: core (interfaces, models), infrastructure (API services, session) and presentation (screens, BLoCs, routing). Dependencies are registered by hand with GetIt.

Engineering notes

Every screen follows the same layout: the screen, a view mixin, a bloc/cubit and a components folder.
