Senior Product Owner and iOS developer with 25+ years of experience. I think in products and speak the language of developers.
Freelance Services
Martin works as a freelance Senior Product Owner and IT consultant. His edge: he can code. That means he asks the right questions, understands technical trade-offs, and doesn’t need things explained twice.
Backlog management, user stories, sprint planning, release management and stakeholder alignment. Comfortable in Scrum or Kanban, across mobile and web products.
App strategy, architecture decisions, team setup and developer coordination. Strong on iOS-first and Flutter cross-platform products where technical trade-offs shape the roadmap.
End-to-end responsibility for a mobile product — roadmap, backlog and App Store release. The owner role when a team is between hires or scaling fast.
Apps
These are my own apps — designed, built and published by me.
