Hello, I'm
Mohammed Ammar
Electronics Engineer | PCB Design Specialist | Embedded Systems Developer
I turn your idea into a real electronic product — from the first sketch to a board ready for manufacturing.
About Me
I am an Electronics Engineer based in Egypt, currently advancing my studies at the Faculty of Engineering,Electronics and Communications Department. My passion lies at the intersection of hardware innovation and precise engineering.
I specialize in translating complex ideas into manufacturable, high-performance electronic systems. With a strong focus on signal integrity, advanced PCB design, and robust embedded firmware, I bridge the gap between theoretical engineering precision and practical, scalable implementation.

How I Work
You Explain Your Idea
Tell me what you need — a quick call, message, or brief is enough to get started.
I Design the Schematic & PCB
I handle the full design — schematic capture, component selection, and PCB layout.
You Review & Approve
You check the design. I apply any feedback until everything is exactly right.
