About the author

Haydar Najm Alhindawi

I have worked in technology since 2007, starting from programming and computer fundamentals, then expanding in 2008 into networking, digital security and practical electronics. That blend of code and circuit shaped how I teach.

My professional identity rests on three pillars: a developer who understands system logic, a practitioner of defensive cyber security, and a hands-on electronics repair technician. I teach the way work happens in the workshop: a step, a reason, and a measurable result.
