SShoply is a modern, feature-rich e-commerce mobile application built with Flutter. It features secure user authentication via Firebase (including Google Sign-In), a dynamic product catalog fetched from Cloud Firestore, and a clean, intuitive UI/UX. The app is designed with a focus on high-quality code and performance.

Flutter, Dart, Firebase (Auth & Firestore), flutter_bloc, go_router, get_it, dartz, hive, equatable.

The main challenge was ensuring the application was scalable and maintainable from the start. To solve this, I implemented a strict Feature-First Clean Architecture, separating the codebase into distinct layers (Data, Domain, Presentation) to promote modularity and make the code easy to test and scale.

Feature-First Clean Architecture. The code is organized by features (e.g., Auth, Products) rather than layers. Each feature has its own data, domain, and presentation folders, while a shared core folder handles global utilities like Dependency Injection and Routing.

A simple but effective Flutter app that generates random numbers within a specified range.

Flutter, Dart, Provider

Ensuring the logic handled edge cases, such as when the minimum value is greater than the maximum value.

MVC Pattern.

A comprehensive Flutter application that combines a powerful calculator with multiple unit converters (Volume, Data, Age, Time, etc.). It features a stunning, responsive UI and is built using Clean Architecture principles to ensure scalability and performance.

Flutter, Dart, Math Expressions Package

The main challenge was implementing a modular system to handle diverse conversion logic (Volume, Time, Data, etc.) while maintaining a clean separation of concerns. I used the Controller Pattern and Dependency Injection to ensure the complex business logic didn't clutter the UI code.

Clean Architecture. The app is strictly divided into Domain (Entities, Use Cases), Data (Models, Repositories), and Presentation (Controllers, Screens) layers.
