Projects

Everything I've built or am building, with its status. Some of it is in production. Some of it is half-soldered. Anything public links to where you can check it.

Every project has its own page: what it does, how it's built, and what it cost.

    EntrenaPro, on Flutter before 1.0

    More than 40 screens on iPhone and Android in four months, on a Flutter that hadn't reached 1.0. Stripe in Dart from the docs, because there was no SDK.
