Senior Software Engineer

High-performance software, built with people in mind.

I'm Nassim, a senior software engineer with 5+ years building web and mobile products across public sector, enterprise, logistics, and cloud. I bridge the gap between users, design, and engineering, shipping interfaces that are fast, inclusive, and genuinely pleasant to use.
