Mobile App Development (iOS / Android) - Node.js / Flutter Expert
Mohsin Ismail was great to work with and handled the project really well. He quickly identified and fixed our API integration issues in a Flutter (Dart) mobile app, improving performance, data sync, and overall stability on both Android and iOS.
Communication was smooth throughout, and his skills in debugging, performance optimization, and backend (Node.js) integration really showed in the final results. The app is now much faster and more reliable.
Would definitely recommend him for Flutter development, mobile app development, and API optimization projects, and would love to work together again!
