Portrait of Maarten Tolhuijs From counterpoint to code.

A different route into engineering

Classical composer turned software engineer.

Before code, there was counterpoint: independent melodic lines working together as one coherent system.

That way of thinking still shapes how I work. I care about the relationships between product decisions, technical constraints, and team dynamics - not just the isolated parts.

Linux curiosity led to Java, then PHP and JavaScript, and ultimately a decade-long career building products and helping engineering teams grow.

“Clear structure creates room for better ideas.”

What should we build next?
