A collection of personal projects, scripts, and experiments — from a GPS-based phone focus tool to C/C++ demos, with CI, linting, and pre-commit hooks across the board.
## Highlights
### [Phone Focus Mode](phone_focus_mode/)
Location-based app restriction for rooted Android. Automatically disables non-whitelisted apps within 500 m of home using ADB + Magisk. Features Haversine distance calculation, hysteresis to prevent toggling, fail-safe unlock, and state persistence. **Bash, Android ADB.**
### [Linux Configuration](linux_configuration/)
Automated Arch Linux setup: fresh-install scripts, i3 window manager config, LaTeX environment, and system tests. Includes documentation and test result logging.
### [Scripts](scripts/)
Utility scripts for development workflows — C/C++ build file validation, secret detection, and custom makepkg helpers.
