How I work
A clear problem, a useful first version, and room to grow.
Understand the problem
Get close to the people using the product. Work out what matters, what’s getting in the way, and what a useful result looks like.
Build something useful
Start with a focused version people can actually use. Make the technical choices that fit the problem and leave room for what comes next.
Learn and improve
Watch what happens in real use. Refine the experience, strengthen the foundations, and automate the work that keeps repeating.
