Saad Bin Khalid

Flutter Mobile App Developer

3+ years building 40+ apps across Fintech, Telematics, and E-commerce

Objective

I care about the details that most skip: saving time for users from 10min to 5s, maintaining >90% accuracy in critical flows, and writing easy code that any developer can understand. My workshops taught 30+ students who never knew Flutter. Looking for a team building something that makes a real difference.
