About Shayan
Full Stack Mobile App Developer (Flutter iOS/Android | Node.js | AI)
Islamabad, Pakistan - 5:12 am local time
Over the past three years, I have successfully integrated complex REST APIs, implemented secure token-based authentication (JWT/Bearer), and leveraged Firebase services (Authentication, Firestore, Cloud Messaging) to build full-featured backend-driven apps. I also have strong experience in Node.js for building scalable backend APIs, RESTful services, and real-time server-side applications. I take pride in writing maintainable code using clean architecture and reusable widgets, ensuring your project is future-proof and easy to scale.
What I bring to your project:
✅ Flutter & Dart Expertise – Custom UI/UX, smooth animations, responsive layouts, and pixel-perfect implementations.
✅ State Management – Proficient in Provider, BLoC, and Cubit to manage app state efficiently and predictably.
✅ Backend Integration – Seamless REST API integration with robust error handling, Dio/http, and secure data transmission.
✅ Firebase Services – Authentication, Cloud Firestore, Realtime Database, and Push Notifications (FCM) for real-time engagement.
✅ Node.js Backend Development – REST APIs, authentication systems, database integration, and scalable server-side architecture.
✅ Performance & Architecture – Clean architecture (layered separation), optimized widget rendering, memory management, and app startup time improvements.
✅ Push Notifications – Full implementation of FCM for targeted, reliable push notifications across platforms.
My objective – To contribute my skills in Flutter development, API integration, Firebase services, and Node.js backend development to build high-quality, user-centered mobile applications, while growing with a strong development team.
