Hello

 I’m Krishna Agarwal — part-time high schooler, full-time tinkerer.

If it can be taken apart, I’ve probably already done it. If it can’t be taken apart… challenge accepted.

My love for building started when I was four and got a LEGO EV3 set. I followed the manual once — just to be polite — and then never touched it again. Since then, I’ve been on a mission to make, break, and re-make anything mechanical I can get my hands on. I’ve fixed guitars, built CO₂ race cars, spring launchers, robotic arms, and even crash detectors (after my mom’s scary car accident). I’ve also accidentally fried a few circuits and broken a TV remote or two. Totally worth it.

For me, engineering isn’t just about wires and screws. It’s about solving problems no one else is thinking about. Like that time my dad forgot his phone and I wished I could’ve just pinged him from across the city — that’s when TagBack was born. Or the time I realized reckless driving happens under the speed limit, so I built a system to detect aggressive turns and braking instead.

I even started the Vishwakarma Club in my school — we’re 70+ strong now, building real-world projects and asking: “Okay, but how do we actually fix this?”

I build because it’s fun. I build because it matters. And yeah — sometimes I break stuff along the way. But that’s where the best ideas start.
