I build teams, software, systems, and useful things for the web.

Projects

Some ideas I’ve been playing with.

A Japanese sentence in Mochiyomi with furigana above the kanji and a dictionary popup for 読みます (to read), with its reading in kana and rōmaji

Live

Mochiyomi

For anyone learning a language, or getting back into one: read real text without stopping to look up every word.

Launched. Paste Japanese, Chinese or Korean text to see how the words are read, and hover or tap any word for its reading and English meanings.

Pixel-art fishing boats on a mountain lake at sunset

Live

pixel.boats

A deliberately tiny place to stop clicking for a minute and watch a boat.

Now afloat. A quiet collection of pixel-art boat scenes with ocean audio, scene shuffling, collections and fullscreen playback.

Retrospan logo above a colorful retro horizon grid

Prototyping

Retrospan

A home for retro-computing experiments: part lab notebook, part toolkit and part hardware field guide.

Expanding the Classics. One home for emulation-era experiments, tools and hardware notes.

Four connected blue cells forming the PCloud mark

Prototyping

PCloud

A personal application cloud where small apps sleep when unused, keep their state and can move between providers.

Cells, not servers. The unit of compute is a user-owned Cell, not a server or container.
