I'm Kai Qian, a Senior Android developer with 9+ years in mobile engineering and over 5 years focused on Android/Kotlin. I deliver high-quality apps using MVVM, Coroutines, Jetpack, and modular architecture, with strong emphasis on performance tuning, threading, offline-first design, and robust API integration. I thrive on fast-paced startups, take ownership, and communicate clearly in remote teams while contributing to multi-module Gradle projects and CI processes. I also have exposure to ML workflows and Python and am eager to deepen Android CameraX/Camera2 competencies. I value maintainable code, thorough testing, and clear documentation, and I aim to continue growing across the full Android stack, including media, offline sync, and scalable architectures.
