I build expressive systems that give complex work a public voice

What I do and why

I'm Jason Yergeau, a developer and writer in Haarlem. For twenty years I've worked between the people who build complicated things and the people who have to understand them. I write the software that holds a body of work together, and the language that carries it to an audience.

Every team I've worked with carries more than it manages to say: research, half-finished experiments, archives, a remark made once in a meeting and never written down. The substance is already there. Expressing it gets left for later, and only a fraction ever reaches anyone else.

What I build are expressive systems for that material. I start from what a team already knows and design something that gives it a steady public voice. This site runs on one. The essays are written by hand; a second layer works quietly around them, surfacing references and drawing lines between related threads. The voice stays mine. The system deepens the reading without talking over it.

What comes out might be a website, a content platform, a run of short video; the form follows the work. Some teams need a site, and I design and ship it without ceremony. Others want the harder thing, a public presence that keeps pace with everything they're doing. I'm at home in both, and most at home in the room where the engineers, the writers, and the people selling the work are all trying to describe the same thing. Translating between them is the part I'm good at.

If your team's public face is thinner than the work behind it, see what I offer.
