How I work

Four steps. At every stage, you know exactly what is being done.

    Discovery

    I learn about your business, your goals and your expectations. A short call or a few messages is all it takes.

  2. II

    Written proposal

    I send the scope, timeline and fee in writing, so what will be delivered, when and at what cost is clear from day one.

  3. III

    Design and development

    You approve the design first, then I build it. Throughout the process, you can review a working preview.

  4. IV

    Launch and beyond

    I launch the project and show you how to use it, and I remain easy to reach long after launch.

The person you talk to is the person who delivers.

On the business side, the day's schedule, confirmations, questions handed over to the team and a monthly report are gathered in a single dashboard.
