À propos de Kenz

Portfolio: kenzenbien.fr
My obsession is building products that people open because they want to, not because they have to.
To me, that means going far beyond writing code. I think about the entire user experience—from the first impression to the smallest details. The interface, micro-interactions, animations, transitions, and that moment when a user understands, within three seconds, exactly what they can do. That's where I thrive.

The plan technique, used in React Native for iOS and Android, has a cross-platform approach that does not sacrifice performance or quality of finish. I have already published additional applications on the App Store and the Play Store, which I have appraised in the following way: the rigor of the process of validation, the keys to the performance of the old devices, the importance of an architecture that is the route to the grand product.
This means that there is a difference in the difference, this is based on the integration of the IA. If you have applications that have artificial intelligence, it is not a gadget marketing collé en surface, but it is also a source of intelligence that transforms the usage: contextual assistants, adaptive generation, functionalities that anticipate the needs. Take a look at the API of the point models (Claude, GPT, Gemini) in long periods of time, latency and experience.
This is what I propose to my clients: a vision product, which is also a pair of mains. If you want to have a letter, the retravaille, the challenge to the design and the book will be an app that honors the idea - on the platform.
Stack : React Native, TypeScript, Expo, Supabase, Firebase, integration LLM (Claude, OpenAI), CI/CD mobile, App Store & Play Store deployment.
