Hi, I'm Vlad 👋
Android developer from Ukraine 🇺🇦
I like small, fast, dependency-free tools that do one thing well.
🔧 What I do
- Native Android apps in Kotlin — launchers, keyboards, system utilities, overlays and foreground services
- Lightweight web tooling — minimal PHP engines without frameworks or heavy dependencies
📌 Featured projects
| Project | Description |
|---|---|
| Darker | Dims your screen beyond system limits using a pass-through foreground-service overlay. Tiny and native. |
| Sheaf-launcher | Minimal home-screen launcher with free-form widgets, a 2D page matrix and per-item z-order. |
| VKeyboard | Customizable, lightweight virtual keyboard for Android. |
🚧 Currently building
- SimpleMd4PHP — a Markdown-driven site engine for PHP servers (powers my personal site)
- Warehousy — an Android app with a dynamic UI layer: JavaScript (QuickJS) scripts bridged to native Kotlin
- A modular file manager for Android — code editor, gallery and music player as optional, separately installable modules
💡 Interests
- Android internals — services, overlays, input methods, launchers, how the system really works under the hood
- Minimal software design — doing more with less code and zero dependencies
- Embedding scripting engines (QuickJS) into native apps
- Microcontrollers and SBCs — Arduino, ESP32, STM32, Raspberry Pi Zero
- UAVs and drones
- Automation and smart home
- P2P networks
- 3D printers
- Finding the weak spots in "locked-down" systems
🧭 Principles
- Fewer dependencies → fewer surprises
- Small APKs, fast startup, no trackers
- “You can’t” is just a hypothesis I like to test
