Architect and builder of privacy-first, on-device software — Apple-Silicon-native tools, end-to-end-encrypted messaging, and document tooling. Founder of Calida Lab.
I build software that runs on your device, under your control — local-first, sudoless, and honest about what it can (and can't) measure.
Apple Silicon & on-device
- SiliconScope — a sudoless Apple-Silicon system
monitor (native SwiftUI) with first-class ANE / Media Engine / memory-bandwidth tracking
and a local-LLM "AI Workload" cockpit. Signed & notarized. · site
- SpectArk — versioned incremental backup for macOS: back up only what's precious (your source), not the whole system. APFS snapshots, in-app restore, scheduled/realtime, NAS.
- Spectalo — on-device AI video player: Whisper subtitles
- translation, entirely on your Mac/iPad.
- SpectaLing — on-device transcription + live translation for Mac/iPad — a privacy-first MacWhisper alternative.
- HWPad — iPad HWP/HWPX viewer + Apple Pencil annotation, on the rhwp engine. Free on the App Store.
Privacy & sovereign systems
- SnowChat — a sovereign community stack on Solana: E2EE messenger (Signal protocol), on-chain marketplace, community fund. (+ SnowClaw, an E2EE on-device AI agent.)
- dart-signal-protocol — a pure-Dart implementation of the Signal Protocol, with zero native dependencies.

Privacy by architecture, not policy. Nothing leaves your device.
