I’m a Flutter Developer and Mobile App Developer building production apps for iOS and Android.
I'm Muhammad Haddi, a Flutter freelancer and mobile app developer in Lahore with 3+ years shipping scalable Android & iOS apps in Flutter & Dart — plus Node.js, MongoDB, and Firebase backend solutions.
Mobile-first developer, full-stack mindset.
I'm a results-driven Flutter developer who turns ideas into scalable, store-ready mobile apps. Over the last three years I've built enterprise CRM platforms, subscription products, real-time communication apps and cloud-integrated tools — for Android and iOS alike.
My work covers the full picture: clean Riverpod architecture and reusable UI on the front, and Node.js + MongoDB services, REST APIs and AWS SES email infrastructure on the back. I care about clean code, performance, and shipping things people actually use.
I've published and maintained apps on both stores, collaborated across cross-functional teams, and worked end-to-end through the software development lifecycle. Open to freelance and full-time roles — remote or on-site.
