I’m an independent Android developer and open-source builder focused on media playback, streaming workflows, polished interfaces, and practical offline-first tools. I enjoy taking complex media features and turning them into clear, reliable experiences.

An ad-free Android media player built around MPV/libmpv and Native Media3. It combines high-quality local and network playback with HDR and Dolby Vision-capable native playback paths, per-video display controls, subtitles, lyrics, Jellyfin, catalog browsing, authenticated yt-dlp downloads, and a modern player interface.

Highlights: Native Media3 + MPV playback · HDR/Dolby Vision paths · per-video aspect ratio, crop, zoom and pan · Jellyfin and network media · catalogs and resolvers · WebView cookie sessions · Quick Download · subtitles and lyrics

A private, offline-first reader for Android and desktop that opens books and dictionaries directly from device folders.

Highlights: Local-first reading · folder-based libraries · Android and desktop support · no unnecessary cloud dependency
