Ask Harold
Our own private algorithmic assistant for everyday tech questions, built privacy-first on the same principles we teach. Harold is the heart of a growing family of specialized algorithmic assistants in development. Your data stays yours.
Work & Projects
Built with purpose.
Crafted with care.
A collection of shipped products, experimental prototypes, and structured research — each built with intention, precision, and a clear point of view.
Shipped
Products
Finished, released applications, polished and ready for the world.
New products in development
The next generation of Distributed Technologies products is actively being built. More to come.
In Progress
Prototypes
Unreleased and work-in-progress projects — a window into what's on the horizon.
Movement Health
A mobile health intelligence tool that identifies and surfaces meaningful trends in your Apple HealthKit and Google Health Connect data. It delivers timely, targeted notifications and actionable guidance when patterns in your movement, sleep, and activity actually matter.
TikTok Archive Viewer
A local-first web application for browsing your TikTok data export. Search, filter, and rediscover your content without sending a single byte back to the platform.
Email Archive Reader
A cross-platform desktop application for importing and browsing email archives entirely offline. Supports MBOX, EML, and folder-based imports, with full-text search, thread view, label management, saved searches, and attachment tracking. Your email stays on your machine.
Explorations
Research
Structured investigations and findings — important work that lives outside the product lifecycle, but is no less worth sharing.
Local LLM Dev Platform
A structured investigation into developer tooling for running large language models on local hardware — covering benchmarking methodologies, workflow orchestration, and infrastructure patterns for fully sovereign, local inference.
Agentic IT Helper
A private, self-contained algorithmic agent for everyday IT support on Windows and Mac. It triages issues, walks through fixes step by step, and escalates to a human expert technician when a problem requires it. Human approval is built into every response and action by design, not bolted on afterward.
Algorithmic Trading Research Platform
A fourteen-service serverless platform for digital asset trading research — technical indicators, on-chain metrics, newsstand and social sentiment, AI analyst personas, year-scale backtesting, and AI-guided strategy optimization that outperforms grid and random search at equivalent iteration budgets.

Hardware Authenticator
Built for users who face the highest threat of device compromise — journalists, executives, activists, and anyone operating in environments where even the operating system cannot be trusted. Hardware Authenticator was an Android application that used a direct path from the Trusted Execution Environment (TEE) to the display for OTP passcodes: the codes were generated and rendered entirely within the secure enclave, and pushed directly to the display at the hardware level. No app — not even the OS — could read or intercept the passcode in transit.
This architecture closed a long-standing attack surface present in every conventional authenticator app, where passcodes pass through the OS before reaching the screen, leaving a window open to malware, screen-capture exploits, and accessibility-layer attacks. By severing that path entirely, Hardware Authenticator offered a level of credential protection that software alone cannot replicate.
The product was fully shipped and released. It has since been discontinued.
