How a project runs · changelog

Every project reads like a changelog.

Scope is written down before code is written. You see a working build at every milestone, and the handover means your next engineer never has to call me.

  1. v0.1 · intro call, 30 min, free

    Is this the right fit?

    We talk through the problem, the users and the deadline. If I am not the right person, I say so and point you to someone who is.

  2. v0.5 · proposal

    Fixed scope, fixed price, in writing

    A short plan with milestones, what is out of scope, and a price. You sign off before any code exists.

    • Milestone list with a demo at each one
    • Changes priced before they happen
  3. v1.0 · build

    A build you can open at every milestone

    Install it, click around, send notes. Each milestone ships with a short changelog of what moved and what is next.

  4. v1.x · launch and handover

    Release, monitoring, and a recorded walkthrough

    Store submission or production deploy, crash and uptime monitoring, documentation, and a video walkthrough so the codebase outlives the engagement.
