Mohamad Alhaj Rahmoun
Software engineer. I build things that scale and sometimes, things just for myself.
I specialize in backend systems, API design, and performance optimization across production Rails applications. Since 2018 I've worked across healthcare, fintech, and edtech shipping features that handle real load for real users. Outside of work, I build my own apps and tools.

Story-driven activity tracker. Walk with Nasheet and discover authentic cultural stories with every destination you unlock.
