Own apps
Small, focused applications for work that takes too much time or manual effort — first for myself, then for anyone they help.
Own apps, experiments, and tools
Digital craft, deeply rooted.
HearthCode Studio is my own workshop. I build digital products I want to use myself, make prototypes to figure something out, and now and then help a friend with a problem they are stuck on.
What takes shape here
Experiments
Prototypes and sketches to understand an idea, technique, or approach. Some grow further; others stay a lesson well learned.
Thinking along
Now and then I help friends with direction, feasibility, and technical choices. Out of interest, not as a service.
HearthCode
How I work
Every project starts with clarity. First decide what is needed, deliberately choose what can stay out, then build in manageable steps.
- 01
Understand
I bring the goal, audience, and constraints back to one clear problem.
- 02
Shape
I turn that problem into a compact approach with visible choices and boundaries.
- 03
Build and improve
I build, test, and improve in small steps so the result stays understandable and maintainable.
AI helps me research, compare, and test. The choices, quality, and responsibility remain mine.
Studio
The maker behind the studio
I’m Wijnand. HearthCode Studio is the name I make my own work under: from the first analysis through design, development, and delivery.
Twenty years at the intersection of business and technology taught me how to turn complex questions into workable choices. I keep that way of working, now that I mostly build for myself.
My measure: the result must be useful, remain understandable, and fit the people who work with it.
