The Mobify team
A focused Flutter-first squad. Senior mobile engineers, product designers, backend specialists, and QA / release managers collaborate on every project, scaled from 2 to 10 people based on scope.
Senior Flutter engineers
Architecture, feature delivery, performance, and complex UI on top of Riverpod 3, go_router, and Clean Architecture.
Product & UI designers
Information architecture, design systems, and high-fidelity prototypes that ship 1:1 in Flutter.
Backend engineers
Supabase, Firebase, REST APIs, and integrations like Stripe Connect, RevenueCat, and Google Maps.
QA & release management
Test planning on TestFlight and Play internal tracks, store submission, and post-release triage with Sentry.
Product management
Discovery, scoping, milestone planning, and ongoing product iteration based on real usage data.
Tech lead & architecture
Architectural reviews, code quality gates, and continuity across the lifetime of each project.

How our team works with Flutter
Our production stack is opinionated and stable across projects. The same architectural primitives scale from a focused MVP to a multi-role marketplace with payments, geolocation, and real-time messaging.
Architecture & code organization
Feature-first modular architecture — each module owns its api/, repositories/, providers/, models/, and ui/.
Clean separation of layers: Presentation → State (Riverpod) → Repository → API → Entity.
Sealed union types via Freezed for domain modeling (e.g. User = Authenticated | Anonymous | Loading) and Dart 3 pattern matching.
Repositories compose multiple services (API + Storage + Messaging) and orchestrate transactional flows like "create mission + parallel photo upload + open conversation".
Centralized enums for backend identifiers (tables, RPCs, buckets, edge functions) — a single source of truth.
State management — Riverpod 3
Riverpod 3.x with @Riverpod annotation and code generation (riverpod_generator + build_runner).
Strict separation between persistent providers (keepAlive: true) and ephemeral ones, scoped per feature.
Custom OnStartService interface to orchestrate ordered service initialization at boot (SharedPrefs → Locale → UserState → UserInfos → Documents → Stripe → Notifications).
Notifiers expose typed state (List<T>, sealed unions, AppLocale) and explicit imperative methods (load, create, update, delete).
Provider composition with ref.watch / ref.read / ref.listen and inter-module dependencies.
Navigation & routing
go_router 17 declared inside a Riverpod Provider, so routes can react to authentication state.
Typed AppPage enum with .routePath and .routeName — no hardcoded strings.
Deep linking via app_links and Supabase auth callback handling.
Testing strategy
Unit tests for domain models (Email, Password validators), repositories (with mocktail), and notifier business logic.
Module-level test aggregators that compose smaller test files into a single entry point per module.
Tests run on every refactor: catching regressions on validation chains, deduplication, and exception mapping.
flutter_test + mocktail; clean separation of fakes/mocks per repository under test/modules/<feature>/.
Design system & theming
Centralized design system in lib/style/ with 15 dedicated style files (colors, typography, buttons, forms, cards, sheets, dialogs, pickers, selectors, sizes, layout, indicators, toasts, snackbars).
AppThemeColors abstraction with full light/dark theme parity.
28 reusable widgets in widgets_lib/ (buttons, cards, forms, navbar, pickers, sheets, image grids, star rating, photo editor, video player, camera, …).
Animations and accessibility considered as part of the system, not an afterthought.
Internationalization
slang + slang_flutter for type-safe i18n with code-generated AppLocale.
Two languages shipped (English, French), hot-switchable from a Riverpod LocaleNotifier.
User locale persisted across launches via SharedPreferences.
Backend & integrations
Supabase (Postgres + Auth + Storage + Edge Functions) as the primary backend.
Stripe Connect onboarding via WebView for professional accounts; RevenueCat for subscriptions.
Firebase Messaging for push, flutter_local_notifications for local scheduling.
Custom Dio HttpClient with bearer-token interceptor; google_sign_in and sign_in_with_apple for native auth.
Sentry for crash reporting; structured logging with the logger package.
Code quality & tooling
flutter_lints with a strict analysis_options.yaml.
FVM for reproducible Flutter SDK versions across machines.
build_runner pipeline for Freezed, json_serializable, and riverpod_generator.
Permission handling, secure storage (flutter_secure_storage), and crypto for sensitive data.
Technical deep diveShly
Architecture in practice — Shly
A two-sided marketplace connecting clients with home-service professionals. The codebase exemplifies how our team structures Flutter apps that need to scale across many features without becoming a tangled monolith.
Module map
12 feature-first modules under lib/modules/, each self-contained with its own api / repositories / providers / models / ui.
The OnStartService interface lets the app boot a deterministic chain of providers (SharedPreferences → Locale → UserState → UserInfos → Documents → Stripe → Notifications) before the first frame, instead of relying on implicit lazy loading.
Guards are plain widgets — composable, testable, and reactive to Riverpod state. GuardAuth, GuardAuthUserRole, GuardOnboarding and GuardDocumentsVerified can be layered to express any access policy without polluting screens.
Test aggregators per module
// test/modules/authentication/authentication_module_test.dart
import 'providers/models/email_test.dart' as email_test;
import 'providers/models/password_test.dart' as password_test;
import 'providers/models/signin_state_test.dart' as signin_state_test;
import 'repositories/exceptions/authentication_exceptions_test.dart'
as auth_exceptions_test;
import 'repositories/authentication_repository_test.dart'
as auth_repository_test;
void main() {
email_test.main();
password_test.main();
signin_state_test.main();
auth_exceptions_test.main();
auth_repository_test.main();
}
Each module exposes a single aggregator entry point — easy to wire into CI, easy to scope a focused run, and a clear convention for new contributors.
