Local Encrypted Document Vault

A local encrypted vault for a folder of sensitive documents, written in Rust. Contents and filenames are both encrypted at rest with XChaCha20-Poly1305; documents are checked out one at a time and re-encrypted when you are done. No network, no service, no account — one statically linked binary on one machine.

Endless Themed Word Search for Android and iOS

An endless themed word search puzzle book for tablets, shipping as two native builds — Kotlin with Jetpack Compose on Android, Swift with SwiftUI on iOS — kept identical by a parity suite that asserts a seed produces the same grid on both. Generates puzzles on demand from a curated 11,281-word corpus across 42 themes, keeps one puzzle in progress across sessions, and never runs out of material. No fail state, no gating, no ads, no trackers, no network.

Multi-Agent Software Development Orchestration
