n‑of‑m Free

Shamir's Secret Sharing for recovery phrases. Split a seed phrase into m printable share cards of which any n reconstruct it, so no single card is worth anything on its own. Splitting and recovery run entirely on your device; nothing is transmitted. Available on iOS and on the web.

Price Free. No account, no subscription, nothing to charge.
Platforms iOS app and browser
HeartRate Broadcaster See product site

Turns an Apple Watch and AirPods Pro into a standard Bluetooth heart rate strap, so gym equipment, cycling computers, and training apps that expect a chest strap can read from hardware you already wear. Broadcasts over the standard BLE heart rate profile, so nothing needs to know it is an Apple device on the other end.

Availability Current price and download route are on the product site.
FinderPasskey Free beta

macOS app that encrypts files and folders from the Finder and unlocks them with a passkey — Touch ID or your device credential — instead of a password you have to remember. AES‑256‑GCM, encrypted locally, keys never leave the machine.

Price Free during beta. Paid tiers are not yet on sale; this page will list the price before any charge exists.

Bespoke services

Two kinds of commissioned work, both booked hourly against a written scope: illustration by Natasha Pankina, and software engineering — web applications, data pipelines, document and media processing, on-device machine learning, and deployment on Cloudflare infrastructure.

There is no self-serve checkout for either. Work is scoped and quoted first, and no charge exists until a quote is agreed. Rates, how an engagement runs, and how to book time are on the services page.

Bespoke services and rates

Development & open source

Roughly thirty side projects — iOS and macOS applications, developer tooling, embedded audio codecs, semantic search, on-chain art, and a set of internal dashboards. Some are published and open source, some are still private, and none of them are for sale.

They are listed newest first, with screenshots where there is something to look at. Unpublished projects carry a badge and a thumbs-up button — if you want one released, that vote is the signal we go by.
