I'm Cao Thiem Nguyen, an iOS & Mobile Developer in Hanoi crafting reliable applications across iOS, Android and Flutter.
I turn complex product requirements into focused, dependable mobile experiences. My work spans security cameras, smart-home and networking devices, social platforms, chat and voice/video calls, e-commerce and in-app payments.
I care about thoughtful architecture, performance, memory management and a smooth release process—from certificates and provisioning to Jenkins and Fastlane.
