Hardware, software and the machines they run on.

Hiring for one role? Its tab is above. Everything else is below.

Computer Engineering graduate from Ajman University. I work across embedded systems, full-stack web and IoT: CubeSat communication hardware, real-time firmware on ESP32 and STM32, custom PCBs from schematic to layout, and the web dashboards that show the data. I like projects where the hardware and the software have to meet.
