Mobile developer based in Hanoi, Vietnam with 3 years of professional experience building production Android applications. My background spans from high-level Kotlin/Jetpack Compose down to C++ native libraries and JNI integration — including a 5x performance improvement on an audio processing engine by migrating core logic from Kotlin to C++.
I also have hands-on experience with cross-platform development (Flutter, React Native) across domains including music technology, e-commerce, AR, and factory management.
Currently expanding into AI/ML with a focus on how it intersects with mobile and embedded systems — on-device inference, model optimization, and edge deployment.
Mobile
- Android — Kotlin, Java, C++/NDK, JNI, Jetpack Compose, MVVM
- Cross-platform — Flutter, React Native (Expo), TypeScript
Other
- C++ (native audio processing, shared libraries)
- Python (ML experimentation, scripting)
- Firebase · REST APIs · ARCore · Git
- On-device ML — TFLite, int8 quantization, embedded inference
- Machine learning fundamentals — neural networks, optimization, PyTorch
- Information Systems (B.Eng.) at Posts and Telecommunications Institute of Technology (PTIT)
Most of my production work lives in private or client repositories. I'm actively working on open-source projects to better represent my work here.
