An engineer who has built the code, the teams and the company.

For more than 20 years I have built software products with teams in startups, enterprises and the public sector: as developer, architect, analyst, Scrum Master and Product Owner. I also founded and led a consultancy of more than 100 people, built on self-organizing teams without middle management. I bring that experience to every level: your code, your team and your organization.

With the allwerker cooperative

Whole features with a team of three.

Most business software doesn’t need a frontend team, a backend team and an API between them. With plain Java from the database to the button, two or three people can own every feature end to end, and AI agents take the routine work off their hands. Together with my colleagues at allwerker, I set up, staff and coach such teams, working in Shape Up-style cycles.

  • Spring Boot
  • Apache Wicket
  • Spring Modulith
  • MongoDB
  • Shape Up

  1. 1–2 days

    Fit check

    A workshop on your product and team: we cut the domain into slices, shape the first pitch and give you an honest go or no-go.

  2. Up to 6 weeks

    First cycle

    Repository, modules, architecture tests, CI and hosting, and the first shaped project in production within its appetite.

  3. Ongoing

    Run & coach

    As pairing and mob partners, or as the team itself: shaping, betting, building, cool-down. You decide how far we step back.
