Hans Bossenbroek is one of the founders and Chief Executive of Luminis. After a long career working for consultancy organisations and doing freelance jobs, Hans concluded that the potential of IT, the inherent complexity of software engineering and the power of innovation can only be unlocked by harnessing the power of the collective. It may seem strange, but this coincides with his love for jazz music, diving and mountaineering. They all build upon the aptitude, discipline and persistence of the individual in a team.
This complex reality is aptly described by Neil Young: “It’s better to burn out than to fade away”.

Robin van Kaathoven
Robin is an opinionated IT Consultant. Efficiency drives his goal-driven approach to building value for customers. A development process can always be improved upon, your use-cases can always be sharper, your versioning rules can always be cleaner, and your business can always evolve into something more.
The ‘business’ is not a boogieman trying to stop us from coding, we just need to help them understand what we need to code efficiently. Robin will help the business get what they need (not what they think they want) and empower the technicians to create the transcended solutions for users they so covet.”

I’m a designer with a broad experience in creating (web) applications and other digital experiences. I believe that you can’t be the best at what you do when you only do what you are best at. That is why I also write about product development and everyday human/technology relations. And I try to code. That doesn’t make me a writer or an engineer, but I believe it makes me a better designer.
