Mobile Apps expert in Lille
I develop mobile apps using two complementary approaches: PWAs (Progressive Web Apps) installed directly from the browser, offering most native features without going through the app stores; and React Native applications that target both iOS and Android from a single codebase.
Dual Engineer + Marketing background (HEC Paris), 200+ projects delivered for SMEs, startups and large corporations. My approach: tailor-made solutions adapted to your sector and your clients.
