Octy

A web builder where people create Android and iOS apps without writing code. I built the engine that turns a project from the builder into a real iOS app.

01 · The problem

A drawing has to become an app

In Octy, people who don't write code put an app together in the browser: screens, buttons and where each one leads. That drawing then has to become a real native app that builds and runs on a phone.

02 · What I built

What I built

  1. iOS code generation engine

    Built from scratch: it turns a project from the builder into a real iOS app.

    A drawing becomes a real iOS app.

    Illustrative

    Drag blocks into the drawing, or focus one and press Enter.

    Drag a block to reorder it, or use the arrow keys. Drag it out or press Delete to remove it.

  2. Graph-based project validation

    Checks a project in several layers using graph logic, so errors are caught early.

  3. Key-frame versioning

    Snapshots at key frames, so users can go back to earlier versions of their app.

    See how it works

    Save points: go back to any version.

  4. Content sharing

    A secure and fast sharing system built on CQRS and caching.

  5. AI assistant

    Generates data for the app engines, using the OpenAI API and Socket.io.
