Leading two teams and 13 engineers who own Marketing and Advertising products at the largest e-commerce platform in the Benelux.

The teams

Two teams, 13 engineers, on a GCP, Java and Kotlin stack. Their products serve millions of daily users across the Netherlands and Belgium. I work with product and design on the roadmap for the marketing platform.

What changed

  • Team topology and service ownership. I redesigned both, sharpening the bounded contexts. Delivery friction went down and cross-team alignment improved.
  • A smaller advertising stack. We decommissioned legacy services, which cut maintenance overhead and made iteration faster.
  • Attribution and reach. We delivered a major attribution migration and a new advertising channel integration, expanding measurement coverage and campaign reach.
  • A bigger team. Through a restructuring I hired five engineers, introduced new ways of working and rebuilt onboarding to shorten time to productivity.

AI in the daily work

I drive the AI transformation agenda for the teams: hands-on AI engineering training, and AI-assisted workflows embedded in day-to-day development.

Every engineer on the teams now uses an AI coding assistant. The clearest result so far: a project estimated at two months was finished in a single sprint.
