I design, build, publish, and maintain mobile products from the first idea through long-term release support. My work centers on modern Android development, privacy-conscious product design, offline-first experiences, and thoughtful platform integration.

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. |
An offline-first encrypted vault for passwords, private records, attachments, backups, and secure everyday access. Google Play → |
A rootless Android utility that adapts display refresh rate to real interaction while respecting device-specific behavior. Source code → |
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 → |

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.

AlpWare Studio is the independent product studio behind my published applications and open-source work. It focuses on useful, understandable software built with respect for privacy, platform conventions, and long-term maintainability.
