How I Design a Project
The best way to understand my working method is to see it in action.
This website — which you are currently viewing — is a good example. I designed it as a real client project, with method, intention, and rigor. For this, I rely on my development skills, but also on reflective tools like ChatGPT, which assists me in structuring content and challenging my ideas.
Every decision is made with the visitors in mind: their profile, their expectations, their need for reassurance. I proceed iteratively, testing ideas, always keeping the end user in mind.
Want to see how I do it concretely? I have documented my approach step by step.
