I build smart homes
and break bad security.

I’m Simratpal Singh — founder of Starvis and an independent security researcher turning curious ideas into useful, real-world systems.

Curiosity is my
favorite tool.

I like understanding how things work — then making them feel simpler, safer, and more human. I started with hardware, grew into software, and found a natural home in security research.

Today, I’m building Starvis: smart home products that solve a real problem, from the circuit board to the app in your hand.

Behind the build

From a rough board
to a working product.

Hardware is not just a render. It is testing, rewiring, learning, and trying again.
