The Engineer Behind Vman Builds
On A Mission to Make Electronics and Software Accessible
Vijay Madas
I’m Vijay — an engineer and educator passionate about making electronics and software easier to learn.
From over a decade of teaching experience and a wealth of maker expertise, I created Vman Builds to help makers go from zero to confident builders. Using clear, practical tools that make engineering easy to understand and apply. If you're starting fresh or levelling up, I'm here to make the journey simple, hands-on, and genuinely fun.
