I build and ship mobile products with a strong focus on Android, privacy-conscious architecture, offline-first experiences, and platform-level tooling — from product idea and interface to release and long-term maintenance.
My work sits between product engineering and the Android platform: polished end-user apps on one side, system-aware utilities and open-source experiments on the other.
| Mobile products Production applications built with Kotlin, Jetpack Compose, and Flutter. | Android systems Utilities that work carefully with platform services, permissions, and device behavior. | Open development Source code, engineering decisions, documentation, and community-ready projects. |
 A rootless Android utility that adapts display refresh rate to real interaction while respecting device-specific behavior. Source code → |  An offline-first encrypted vault for passwords, private records, attachments, backups, and secure everyday access. Google Play → |
 A privacy-respecting internet radio app with background audio, widgets, Android Auto, CarPlay, and shared playback state. Source code → |  A modern QR and barcode toolkit for scanning, creation, customization, organization, and secure offline use. Google Play → |
 System-level physical keyboard layouts for Android, integrated through the platform layout provider instead of a custom IME. Google Play → |  On-device Wi-Fi analysis that evaluates interference, channel width, overlap, signal strength, and confidence to recommend better channels. Google Play → |
| Project | Built for | Availability |
|---|---|---|

| Wakeon | Cross-platform Wake-on-LAN device management | Google Play · Source |
| DarkSwitch | Rootless per-app Force Dark experiments powered by Shizuku, foreground detection, strategy fallback, and an offline compatibility database | Source |
| ChargeFreeze | Rootless Android charging control that pauses battery charging while keeping USB connections active, built for Android Auto, DeX, ADB, tethering, and other long-running connected use cases | Source |
| LeadMailFinder | Open-source company discovery, email extraction, and outreach tooling for job seekers and B2B prospecting | Source |
| Play Store Launcher | A deliberately tiny Android TV utility that exposes and launches the hidden Google Play Store without unnecessary permissions or background work | Source |
| Zapret macOS Discord | A focused one-command Zapret setup for Discord on Apple Silicon Macs, covering installation, configuration, and networking behavior | Source |
Privacy-first — collect less, keep sensitive work on-device, and explain network behavior clearly.
Offline-first — keep core experiences useful without requiring a permanent connection.
Platform-aware — use native capabilities when they create a more reliable and coherent product.
Long-term — treat publishing as the beginning of maintenance, not the end of development.

I build and publish my independent products under AlpWare Studio — focused on useful, understandable software shaped by privacy, simplicity, platform conventions, and long-term maintainability.
