The Cartographer

Anatolii Ternytskyi builds apps for phones and the web, and the servers behind them, in one language: Dart.

I start with the screen a tired person will really use: a seat map on a long bus ride, a price tag in a supermarket aisle, a courier's dot crawling across a map. If an app holds up there, it holds up anywhere.

I like small crews, honest estimates and code the next person can read without a guide. The engravings on this site are drawn with code as well: a few hundred lines of numpy, no stock art.

Sailing directions

  • Offline is a feature, not an error state.
  • Ship the plain version first, then make it beautiful.
  • Every screen should survive a slow network and an impatient thumb.
