A specific feature or support over several weeks, depending on your need.

  1. Your need

    Show me what is blocking progress, your application and the tools you use. A short description is enough to start the conversation.

  2. An agreed scope

    We define the deliverables, acceptance criteria, budget and schedule before starting.

  3. Implementation and handover

    I develop, test and prepare the release. You receive the code, useful documentation and a handover with your team.
