Hi! I'm Raoul. I work in tech under the brand World-wize.

Software systems are now ubiquitous, but their potential is still rapidly expanding.

What do I get involved in?

I work as a business-aware technical consultant in start-ups and mid-size companies. I help my clients tackle high-growth phases sanely and responsibly, by advising on software management and development. I like responsible organisations with a strong purpose.
