N. V. Hiền

I’m a Software Developer with a strong focus on building cross-platform applications using Flutter for Android, iOS, and Web.

I have experience developing and maintaining production applications, including UI implementation, business logic, API integration, Firebase, and applications that communicate with hardware through Bluetooth Low Energy (BLE), USB, and OTA/DFU firmware updates.

In addition to client-side development, I also work with backend services and APIs, which allows me to handle features across the full application flow, from the mobile or web client to server-side logic and data processing.

My experience also includes maintaining existing products, implementing new features, troubleshooting production issues, handling compatibility across different device and firmware versions, and preparing applications for release on Google Play and the App Store.

I also maintain an open-source Flutter package, flutter_ble_connection_manager, focused on managing BLE connections in Flutter applications.

I’m currently looking for freelance projects involving Flutter, cross-platform development, backend/API development, BLE/IoT, Firebase, application maintenance, bug fixing, or feature development for existing products.
