01 · Selected work
Two products I care deeply about, where systems engineering and product UX had to meet the same high standard.
An advanced all-in-one Android tool.
FlashFlow is a cross-platform tool for Android power users. It supports Pixel, OnePlus and Xiaomi devices with bootloader unlock/lock, flashing stock ROMs, OTA, factory images, AOSP, Super.img, and custom recoveries like TWRP and OrangeFox.
A minimal, ultra-fast Android keyboard.
FBoard is a modern Android keyboard focused on typing speed. It avoids bloated features and keeps only what matters for a smooth typing experience.
Smaller tools, held to the same standard of finish.
macOS Flasher
A macOS-optimized flasher for OnePlus devices.
Ddrop
High-speed file transfer between Android and macOS.

03 · Approach
Every line of code matters. I don't just write software that runs; I build systems that are optimized, stable, and aesthetically refined. Whether it's a macOS system tool or a demanding Android app, simplicity and user experience are always the guiding principles.
Mastering System-level, Native Apps, and Web Frontend. Instead of patchwork solutions, I focus on solid architecture, latency optimization, and strict adherence to each OS's UI/UX standards (Apple Human Interface & Google Material).
