You will get Rest APIs & Backend Development with Node.js & ExpressJS
Project details
I create robust and scalable backend systems and APIs using Node.js, Express.js, and modern database solutions like MongoDB, PostgreSQL, and Firebase. I develop secure REST APIs, implement authentication & authorization (JWT, OAuth), and design database schemas optimized for performance. Standard and advanced packages cover CRUD operations, third-party API integrations, real-time features, webhooks, and admin controls. Every project ensures clean code, proper documentation, and scalable architecture, ready for production deployment. I can also integrate payment systems, analytics, and cloud services to make your backend fully functional and ready to connect with your frontend

About Shayan
Full Stack Mobile App Developer (Flutter iOS/Android | Node.js | AI)
Islamabad, Pakistan - 3:53 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.
