Building software that isfaster, smarter,and more sustainable.
Hi, I'm Danny. I build sustainable websites, tools and explore how we can utilise modern web architecture to create digital products that work better for people and planet.

My latest tinkering and experiments.
Not a stream of fleeting takes, but useful notes from real projects: ideas, experiments, and lessons that are still evolving.

So I got curious about Payload CMS with Next.js
Where the thinking becomes building.
I keep coming back to the same practice: build what's needed, build it well, and stay honest about the impact. Each project approaches it differently — and they inform each other. This website is where I share what that looks like.
The company01
Moonsio
Where sustainable software becomes client work. Custom sites, technical strategy, and engineering that stays lean by default.
The initiative02
Pixel to Planet
Together with Merel Witteman: an invitation to take the physical impact behind every digital product seriously.
The tool03
Carbonfooter
Measures the carbon footprint of websites so teams can see the real cost of their pages — with a developer API on the way.
The product — coming soon04
Orbit
Makes website impact and performance visible, so teams can improve with intent.
Three forces, one practice.
The next generation of software should not be defined by one new framework. It will emerge where responsibility, intelligence, and clear technical judgment reinforce each other.
01
More sustainable
Less data, less energy, and less complexity, without compromising what people genuinely need.
02
More intelligent
AI as part of the system: deliberately designed, understandable, and focused on useful work.
03
More human
Good technology expands insight and agency. Judgment remains more important than tooling.
FAQ
Questions I hear a lot.
Straight answers to the questions that come up most, without the sales talk.
Personal, practical, and always evolving.
This is my public knowledge base. I write to think more clearly, show how ideas hold up in practice, and help others make software that earns its place in the world.
