Quem Concerta: a home-services marketplace with in-app quotes

Context and problem

Hiring maintenance, renovation or cleaning is often a headache: finding someone reliable, explaining the job and comparing prices. Quem Concerta brings customers and home-service providers together in one place.

My responsibility

• Mobile development in Flutter of the customer and provider flows.

Solution

For customers: service requests with description, photos and videos, scheduling, chat with the provider and reviews.

For providers: incoming requests on the home screen, filtering by distance, description and photo, and building quotes on the phone with items, prices and attachments, then reviewing and sending them.

Architecture decisions

• Flutter with Clean Architecture to separate business rules, data and UI across the customer and provider flows.
• Firebase as the backend.

Stack

• Flutter
• Dart
• Firebase
• Clean Architecture

Results

Request, quote, scheduling and review in one app

Providers build and send quotes straight from their phones
