I'm Muhammad Nisar, a Flutter Developer with 2+ years of experience building mobile applications for Android and iOS.
Most of my work has been around turning ideas into complete, working applications — from designing the mobile side in Flutter to connecting it with APIs, databases, and backend services. I also work with Node.js when a project requires a custom backend or real-time functionality.
My main tools are Flutter, Dart, Node.js, Firebase, MongoDB, REST APIs, WebSockets, and AWS. I've worked on different types of applications and have experience handling features such as authentication, real-time communication, payments, notifications, admin panels, and third-party integrations.
I've worked on projects that have been released for both Android and iOS, and I'm comfortable working on an application from the initial development stage through testing, deployment, and further improvements.
I prefer keeping the codebase organized and practical, so it stays easy to understand, maintain, and build on as the project grows.
