Architect and builder of privacy-first, on-device software — Apple-Silicon-native tools, end-to-end-encrypted messaging, document tooling, and on-chain community systems. 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.
- 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. Developer-ID signed and notarized.
- SnowChat — a sovereign community stack on Solana: an E2EE messenger (Signal protocol), an on-chain marketplace, and a community fund.
- dart-signal-protocol — a pure-Dart implementation of the Signal Protocol, with zero native dependencies.
- HWPad — an iPad HWP / HWPX document viewer with Apple Pencil annotation, built on the rhwp engine. MIT; free on the App Store.
On-device AI, Apple Silicon, end-to-end encryption, document tooling, local-first and sovereign systems.
