OmarHmdea

Embedded Software Engineer

Bare-metal firmware on ARM Cortex-M, system software on embedded Linux, and the test infrastructure that keeps both honest — with measurable reliability gains in production.

On the side I build websites for local organisations as a freelancer, from first sketch to launch.

Things I've
engineered.

    Optical-to-RF radio bridge

    80.6% → 99.8% link reliability
