Crafting
experiences
that scale

I'm a Frontend & Mobile Developer based in Algeria with over 9 years of professional experience building products that people actually use. My craft centers on React Native and React JS, with a deep understanding of what makes an app feel great — from architecture decisions to the last micro-animation.

I've had the privilege of working with some incredible teams — from Yassir, a ride-hailing platform serving millions across North Africa, to Leadific, where I architected SaaS dashboards from the ground up. Today, I lead mobile at Legal Doctrine, owning the full release lifecycle for a legal intelligence platform spanning 5+ African countries.

What sets me apart: I care about the whole product — not just the code. Performance, accessibility, SEO, design systems, CI/CD pipelines — I've owned all of it, and I bring that breadth to every engagement.
