How a project runs

  1. First, we talk.

    A call to understand the goal, the users and the constraints. You get a clear scope and plan.

  2. Then, we agree the plan.

    Architecture, milestones and the look agreed up front, so there are no surprises later.

  3. Next, I build it in the open.

    Small, frequent releases you can click through, with updates every week.

  4. Finally, we launch.

    Deployment, monitoring and a hand-over, with support after launch.
