Vault — Desktop YouTube Downloader

A cross-platform Electron desktop app wrapping yt-dlp and FFmpeg to download video, playlists, and audio from YouTube and other sites, with binaries auto-fetched per platform on first run. Features a concurrent download queue with configurable parallelism, pause/resume/retry, and real-time speed/ETA tracking, backed by a SQLite history store with search, filters, and download-archive deduplication. Includes a post-processing pipeline supporting format/container selection up to 4K resolution, subtitle embedding, metadata/thumbnail/chapter embedding, and SponsorBlock segment removal, plus browser-cookie import for age-gated and members-only content. Built with a polished, self-updating desktop experience — frameless custom titlebar, command palette, light/dark themes, and in-app video preview.

Sanctuary — Church Presentation & Display Platform

A production-ready church presentation application built on a multi-window Electron architecture, delivering zero-latency synchronized outputs to operator, audience, and stage displays via custom IPC Redux broadcasting. Features a seamless, enterprise-grade auto-update engine powered by GitHub Releases and electron-updater for secure, silent background deployments during live services. Includes a high-performance Auto-Fit text engine using requestAnimationFrame and advanced typography scaling to prevent clipping and ensure pixel-perfect projection across variable screen sizes, plus an offline-first data layer with better-sqlite3 and fuse.js for rapid media retrieval, real-time text multi-highlighting, and drag-and-drop service planning.

Shelf UI — Headless File Storage & UI System

A headless file storage abstraction layer with a unified API for file operations, enabling interchangeable storage providers without modifying consumer components. Includes a published MCP (Model Context Protocol) server on npm, exposing Shelf UI components, documentation, and examples as structured tools and resources for AI-assisted code generation and developer workflows. Architected with a scalable adapter system intended to support multiple backends (Supabase Storage, S3-compatible services, Cloudinary), allowing seamless switching between providers at the application layer.
