About

Numispark is a France-based web and mobile development agency. We design, build and maintain custom digital products for clients across France and Europe — mobile applications, booking and marketplace platforms, e-commerce systems and business management tools.

We work with a modern JavaScript stack across mobile and web, and we manage our own production infrastructure. Our engineering culture is remote-first, asynchronous, and built around clear written communication and end-to-end ownership of what we ship.
