Based in Den Helder. Available for remote work.

I lead software teams.
And I still write code.

For more than ten years I have built SaaS products and internal platforms. I work mainly with Laravel, React, and Vue.js, and I am happiest when I can help a team make sound decisions and ship the work.

Experience

I lead teams.
I also ship software.

I work best in roles where I can make technical decisions, unblock people, and still contribute to the product.

Toolbox

The tools I use in practice.

Laravel and PHP are my strongest tools. I also work with React, Vue.js, Linux, Kubernetes, and the wider stack needed to ship a product.

01

Backend & product

PHP, Laravel, SaaS architecture, web applications, APIs, business-critical platforms.

02

Frontend

React, Vue.js, JavaScript, AI-assisted interfaces, and full-stack feature work.

03

Platform

Linux, Kubernetes, command-line workflows, and running software in production.

04

Leadership

Technical direction, mentoring, team leadership, and working across product and engineering.

Portrait of Maarten Tolhuijs From counterpoint to code.

Before software

I studied classical composition.

Before I became a developer, I studied counterpoint and composition at the conservatory in Alkmaar.

Counterpoint is about several independent lines working together without losing the whole. I still recognize that kind of problem in software and teams.

I started programming after getting curious about Linux. Java came first, followed by PHP and JavaScript. I have now worked in software for more than ten years.

It was not the obvious route into engineering, but it turned out to be a good one.
