FULL-STACK SOFTWARE ENGINEER
I build reliable web, mobile & desktop apps for teams around the world.
5+ years shipping production software with React, Next.js, Node.js and React Native, most recently three years remote with a Finnish software company.
I'm Mohammed Fajiran, a full-stack engineer who cares about clean code, clear communication and software that actually ships.
Over five years building dynamic, user-centric applications across web, mobile and desktop. I've worked with clients and teams worldwide, as a freelancer and as a remote engineer, most recently spending nearly three years with Bernersoft in Helsinki, shipping MERN-stack web applications. I pick up new frameworks and tools quickly and work comfortably across timezones.
