Building high-performance, beautiful, and architecturally sound mobile experiences using Clean Architecture & MVVM.
I am a passionate Flutter Developer and a CSE Graduate from Daffodil International University. I specialize in creating scalable, cross-platform mobile applications with clean, modular, and maintainable architectures. Adhering strictly to SOLID principles, Clean Architecture, and MVVM design patterns, I focus on building robust application infrastructures that are easy to test and scale.
Here is a quick snapshot of me:
- 💻 What I've Done: Developed and contributed to production eCommerce applications, Merchant Apps, and Kitchen Display Systems (KDS) using Flutter, REST APIs, state managers (BLoC, Provider, GetX), and local databases.
When I am not writing clean code or designing robust mobile architectures, I enjoy engaging in activities that keep my mind creative and body active:
- 💻 Coding: Learning new tech stacks, designing packages, and building side projects.
- 🏏 Playing Cricket: Actively playing cricket, which helps me stay fit and fosters teamwork.
- 🎵 Listening to Music: Tuning into melodies to find focus and unwind.
- 🎬 Watching Movies: Exploring films, especially sci-fi and thrillers.
- 🎨 Frontend & Frameworks: Flutter (Dart), Responsive UI/UX Implementation
- ⚙️ State Management: BLoC, Provider, GetX, RxDart
- 🌐 APIs & Backend: RESTful APIs, Firebase Suite (Auth, Firestore, Cloud Messaging)
- 💾 Databases & Storage: SQLite (Drift), Hive, SharedPreferences (Session Caching)
- 🏗️ Architectures & Patterns: Clean Architecture, MVVM (Model-View-ViewModel), SOLID Principles, OOP
- 🔧 Tools & Platforms: Git/GitHub, Postman, VS Code, Figma, Linux
