(01) About

I build mobile products that feel effortless — Flutter and native Android apps with clean architecture, real-time features and offline-first data, taken from the first commit all the way to the stores.

I'm a Mobile Software Engineer based in Tunis, currently leading the mobile department at Oxton Digital, where I oversee Flutter and native Android delivery across client projects.

My background is in embedded systems and mechatronics — which is why I enjoy the hard edges of mobile: BLE and Wi-Fi device links, offline-first sync, real-time chat and payment flows that simply work.
