Process

How I work

Scope and priorities are agreed before development. Deliverables are reviewed throughout the project.

  1. Scope

    We define the problem, who it is for and what belongs in the first release.

  2. Design

    I review user flows, content and interface states before implementing them.

  3. Development

    I build the interface, connect the data and test integrations incrementally.

  4. Review and delivery

    I test the flows on mobile and desktop, fix issues and document the handover.
