Process

03 / Process

AI agents in every step. A person who checks every result.

  1. 01

    Plan

    I define the problem, the user, and the smallest product that proves the idea.

  2. 02

    Build

    I build the interface and the backend together, with typed code from the start.

  3. 03

    Test

    I check each change with tests and in a real browser before it counts as done.

  4. 04

    Ship

    I release early, watch real use, and improve the product in small steps.
