Peter Deems, behind Twilight Studio.
Twilight Studio is the name Peter Deems ships under: an independent developer making apps, websites and experimental software. One person, end to end.
What the work covers
The newest project, Easy Talk, is a voice dictation app for Android and Windows: a Kotlin accessibility service on one side, a Rust and React desktop app on the other, and a shared clean-up prompt tested against its own case set.
Around it sit very different problems. A computer-vision bot that reads a game's screen and refuses to act on a misread. A Minecraft server being ported from PHP to Java, with a store and staff panel on one database. A full ordering site for a Columbus bakery. A cross-platform sports app. A paper-trading research prototype built so that it cannot place a real order.
Twilight Studio is not an agency and not a team. When a page here says “built”, Peter built it.
How the projects are made
- 01
Read the source, don't guess
Aetheria's port treats the old PHP as the specification. Bugs came from inventing plausible behaviour, so now the answer is read, not assumed.
- 02
Refuse rather than be wrong
The Clash bot skips a base instead of attacking on a misread. Signal Desk blocks a scan on stale data. Easy Talk keeps the raw transcript when a clean-up comes back implausibly long or short. The on-phone model also falls back when it stops using the speaker's own words.
- 03
Numbers come from tools
Aetheria's status page is generated from the repository, and Easy Talk's clean-up prompt is scored by a script against its own test set.
- 04
Keep the user's data where it belongs
Easy Talk has no server and no account. The Aetheria store cannot touch game state. Signal Desk publishes only a sanitized snapshot, and nothing on the website can place or change a trade.
