About Franck

I develop complete web applications with Next.js and React, from design to deployment. I integrate AI features to automate and enhance your products.
I designed and launched holyfish.fr alone, an A to Z SaaS app: authentication, database, Stripe payment, weather API integration, and AI species recognition.
I work remotely and adapt to the needs of small teams and SMEs that want to move fast without sacrificing quality.
