Back to original languageAbout David
⭐️Product Designer & Developer – 10 years of experience transforming ideas into concrete applications.
I design products with a simple conviction: good design is worthless if it doesn't see the light of day quickly.
That's why I've developed a rare dual role — UX/UI designer and developer — to go fast, well, and straight to the point.
What I'm passionate about: mobile applications, SaaS, and especially the impact of artificial intelligence on how we create.
I now integrate AI from the design phase to save valuable time, avoid unnecessary back-and-forths, and above all, reduce your costs without sacrificing quality.
For design missions, I designed SnappStack, the largest library of UI components: a tool that allows me to deliver solid, modern and consistent interfaces in just a few days.
On the development side, I'm comfortable with native technologies (SwiftUI, React Native...) but I can also go further, faster, with tools like Lovable, combining design + code + AI to create functional MVPs in record time.
If you have an idea, a project or an urgent need, I would be delighted to discuss it with you.
My goal: to help you launch faster, test earlier, and succeed more safely.
