The author after getting married, donning a fabulous tweed

Hi! My name’s Mark Wubben. I’m a humanist & technologist who loves working with the web. In the above picture I’m wearing a fabulous Irish tweed cap. You could send me an email.

Living in Haarlem (the Dutch one) I enjoy the local craft beer scene, as well as Scottish single malts. You might spot me riding an white / orange Brompton bike. You’ll definitely see me at a Hawksley Workman, Whitehorse or Port Cities gig. Priority podcast listens are This American Life & The Talk Show.

Skills & Background

I’ve been working with the web professionally for over ten years. Initially a front-end engineer I’m now interested in backend systems, JavaScript tooling and product development. Currently I work as principal product engineer at Monolith.

Learn more about my skills and background.


I’m the lead maintainer of AVA, a Node.js test runner. I also maintain several other Node.js modules.

I once wrote a bunch of Babel plugins and a Let’s Encrypt / ACME client named wilee. I also developed Buoyant: a framework for building distributed systems using the Raft Consensus Algorithm.

Back in the ES5 era I wrote a small ecosystem of functional promise-based libraries.


I post the occasional tweet or photo. I’m on GitHub and Keybase.
